However, its solution can cause enormous difficulties. In this manual, we will look at one of the most frequently encountered problems and tell you what to do if you are unable to establish a connection with the iPhone software update server.

After launching this mode, you will see a list of all backup files that are on your computer. After scanning, all contents of the backup file are sorted into categories. Now you can select files to recover. First, reboot your device.

An error with the text “Unable to establish contact with the iPhone update server” can occur for several reasons at once, and accordingly, various actions may be required to solve the problem. Below we have discussed several ways to combat this error.

1. Check if your computer has Internet access

After resetting the error should be resolved. If not, you need to restore your device. Now click "Select" to restore your data. The recovery process then begins, which may take longer than an hour in some cases. Select the firmware and download.

You need to download the firmware for your device for it to work. Then click "Download" and wait for the software to finish downloading. Make sure your network settings are correct and that your network connection is active, or try again later. In short, you're stuck and have no idea how to proceed.

Yes, it may sound trivial, but sometimes the problem may be that at the time when iTunes was accessing the Apple software update server, there was no Internet connection on your computer. Therefore, before you begin any active actions, make sure once again that your Mac or PC has access to the Internet.

2. Update iTunes to the latest version

To transfer your subscription more than three times, please contact support. The issue was quickly resolved and we apologize to these customers. The following message is displayed on all error-prone devices. What the heck! Anyone have other problems?

Luckily, the solution to this problem is simple as the error message looks like this: repair. Unfortunately, if you don't back it up, you'll lose all your data that wasn't synced to the cloud. So, in light of the issues that many users are experiencing, our recommendation is to wait a bit for clarity, especially if you haven't created a backup for a variety of reasons.

Step 3. Open the hosts file with any text editor, for example, standard Notepad (you need to open the editor as an administrator)

Step 4. Remove from the hosts files all lines containing the address gs.apple.com

Step 5: Save changes and restart your computer

technical work, or simply “fall”. The latter, however, happens only after the release of the largest updates.

“iTunes cannot verify the authenticity of the server” - this is an annoying message that a user sometimes sees when trying to establish a connection between an i-device and a PC. Yes, iTunes is a stable service, but it is not immune to errors.

Fortunately, the above problem is solved in most cases at the software level and any user can handle it. How? Read in this article.

The error that will be discussed in this material is not the only problem that arises when working with iTunes, and it is logical that each problem requires an individual approach. However, while Apple Support has developed unique solutions for each problem, the engineers have also created, so to speak, a first aid scheme - standard error correction measures that need to be performed before moving on to individual instructions. We recommend starting with them if iTunes reports that it cannot verify the authenticity of the server.

What are these measures? They are quite simple.

Rebooting the program and gadget, and then trying again to perform the operation that was interrupted by the error - the recommendation is, of course, banal, but this does not make it any less effective - the most ordinary reset often saves the situation.

Reconnecting the device

This measure consists of changing the USB port through which the i-device connects to the computer - it is possible that the port being used has stopped working for one reason or another.

Disabling security programs

Often, security services work too hard. iTunes often accesses Apple servers during operation, and the antivirus and/or firewall may consider this behavior suspicious, blacklist the program and prohibit access to the network. Try disabling security utilities for a while and check if the error disappears. If the problem no longer occurs, reconfigure protection services by adding iTunes to the list of trusted programs and enable them again.

Software Update

Outdated software often causes various software conflicts, including problems with iTunes. Therefore, if the above tips did not help, update all programs, starting with iTunes (it is best to completely uninstall the program to update the Apple service, and then install the current version again).

As for updating other programs. On a Mac, updates are located in the App Store section of the same name; if you are working on a Windows PC, click “Start,” enter “Windows Update” in the search bar and press Enter.

Special measures

If standard instructions do not solve the problem, you can take special measures.

Update via iOS device menu

In most cases, a communication error with the server occurs during the process of updating an i-device, so first of all, Apple recommends trying to perform the update not through iTunes, but through the device menu - “Settings” / “General” / “Software Update” / “Download and Install” "

This recommendation may seem strange to some - and, in fact, avoiding the problem is not a solution to the problem. However, in the situation with this error, everything is not so clear. The fact is that communication errors with the server can occur as a result of unstable Internet. For example, there are some problems on the provider’s side, which the latter will soon eliminate and which the user cannot influence in any way. What the user can do is either wait for the problem to be fixed, or update through the device itself, using a different network. From this point of view, Apple's recommendation seems logical.

Editing the hosts file

If the network is working properly, but the error still occurs, then Apple recommends making changes to a special hosts file, which, with certain settings, can block access to the update server.

If you own a Mac, the editing order will be as follows:

If we are talking about a Windows PC, the order in which the file is edited depends on the version of the platform installed on the computer. Detailed instructions for each version can be found

Whether you're using your iOS, Mac, or Windows device to connect to one of Apple's digital content stores, you may be plagued by "Can't connect to the iTunes Store" or "Can't connect to the App Store" errors. This can happen at any time, even the most inconvenient moment, when you try to use the App Store, iBooks store, and even iTunes.

Can't connect to iTunes or App Store on iOS: what to do

If you are having trouble connecting to the App Store, or any of Apple's other online digital content stores through any of your iOS devices, be it an iPhone, iPod or iPad. There could be many reasons why this happens. Sometimes it could be a problem with the wireless network, a disconnected internet cable, or it could be because the drivers are not up to date. You can follow the following steps to help resolve these issues.

Check date and time settings

If the date and time on the device are turned off, Apple's digital content stores obviously won't like it. To check your date and time settings, you need to do the following:

Make sure you have the latest version of iOS installed on your system

Another thing you can check is to make sure your iOS version is up to date. To do this, check for updates; this can be done by following the instructions below.

Make sure you have a good data connection

If you're using Wi-Fi, make sure you're connected to the correct Wi-Fi network by going to Settings and opening Wi-Fi, and that your signal is strong enough.

Checking the Wi-Fi connection settings

If you're on cellular, check to see if you have cellular data set up in Settings > Cellular and make sure your signal is strong enough for a decent network connection. You should use LTE if possible, as it usually has better data speeds.

Enable the use of Cellular

Disabling active VPNs

If you are using a VPN that can block Apple digital content storage, then you should immediately disable the VPN from Settings > VPN to see if you can connect or not. If everything works after disabling your VPN, then the VPN was your problem all along.

Turn off VPN

Do other devices on the same network have the same problem?

You can check whether the problem is just your device or an issue with Apple's servers by testing another iOS device or another Mac or PC to see if those computers are also having connectivity issues. If the problem occurs on all devices, then it is likely that Apple's servers are experiencing an outage and you should try again later.

Make sure there are no problems with your router.

You should never rule out that there may be problems with your wireless router. If you are seeing endless error messages, you can also try resetting your router and thus resetting your internet connection and this may solve the problem.

Can't connect to iTunes or App Store on Mac

As with iOS devices, you may experience similar connection issues when using the Mac App Store, iBooks Store, or iTunes Store. Here are a few steps you can take to fix connection problems on your Mac.

Make sure your software is up to date

Apple's OS X operating system uses two key applications to connect to the web, namely, online digital content stores - Safari and iTunes. If you are using an outdated version of these software products, Apple may block their connection to digital content stores from a security perspective.

You can make sure they're both up to date by launching the Mac App Store and opening the Updates tab, then installing updates if necessary.

Go to the “Updates” tab

Make sure your firewall isn't blocking Apple's digital content stores

Mac users have access to firewall settings, but only for incoming connections. Third-party firewall software such as LittleSnitch will allow you to block outgoing connections. Make sure your incoming and outgoing connections allow you to use the Mac App Store, iBooks, and iTunes.

To check the OS X Firewall's incoming connections, you can launch the System preferences application from the menu in the Menu Bar, then click the Security & Privacy panel and open the Firewall tab. Here you can unlock the firewall settings and click the "Firewall Options" button to configure the allowed and disabled settings.

Unlocking firewall settings

Make sure VPNs aren't blocking access

As with iOS, you can check to see if your Mac is connected to a VPN, which may be restricting access. Generally, VPN software is accessed from the menu bar when it is in use.

Checking if the Mac is connected to the VPN

Resetting your router or modem

Since Mac computers can use a wireless or wired internet connection, you can try resetting your wireless or wired router, this may fix the problem.

Sometimes problems with your router may be the cause of iTunes Store and App Store connection errors.

Check Apple Server Status

To find out if the problem is with Apple's servers and not the Mac, visit the System Status web page and it will alert you to any problems with Apple systems. If all the items are marked green, then the problem is most likely related to your computer and not to the servers.

Can't connect to iTunes or App Store on Windows

If you are having trouble connecting to the iTunes Store on your Windows PC, you can follow some of the following steps and hopefully this will resolve your issue:

Make sure iTunes is up to date

Since Apple is quite strict about keeping software up to date, the problem may be related to an unsupported version of iTunes. Make sure you have the latest version of iTunes installed on your computer.

Check your network settings

Your network connection may be the reason you are unable to connect. Try to make sure you are connected to the correct Wi-Fi network or check if your router is working. You can reset your router if necessary.

Make sure your proxy or VPN isn't causing problems for you

As mentioned in the iOS and Mac troubleshooting steps above, VPN servers and proxy servers can cause problems connecting to certain servers. Try disabling them and try connecting to the iTunes Store again.

Check your antivirus software

Some antivirus software may flag iTunes as a third-party unsafe program, and may block its Internet access privileges. Since antivirus software is common on Windows, this is a great place to check.

Check Apple Server Status

Just like Mac users, Windows users can visit the Apple Server Status web page to see if any of its services are being disabled while trying to connect.

iTunes and App Store connection errors can occur at the most awkward moment when you are trying to download a new game or update an application, it always causes pain and agony. Fortunately, this problem is completely solvable; there are many ways to find the cause of its occurrence and effectively eliminate it.
