Is “Couldn’t Open Connection To Server” Error fixable?

This type of problem usually indicates that a mobile device is having difficulty establishing a link to a remote server in your network operator’s system. As such, the solutions that you can try vary a lot as there’s no specific reason that we can figure out. Generally, you’ll be doing most troubleshooting on your device. If all the suggestions we provide here won’t help, that means that the connection problem you’re having is coming from somewhere else, most likely an issue with your network. That said, the problem is usually fixable on a user’s level. We hope that we can walk you through the steps with our suggested solutions.

What do you need to do to fix “Couldn’t Open Connection To Server”

Below are the troubleshooting steps and potential solutions that you can do to fix this error

Check for online solutions

Some network connection issues are specific to a carrier. In our research, we noticed that couldn’t open connection to server issue is usually experienced by Samsung Galaxy users from AT&T. Try searching Google for the specific error or message that you’re getting to see if other users share the same experience. If you belong to the same network, the problem is most likely a problem coming from your carrier. Make sure that you install any available carrier update and contact your network’s technical support team if the issue continues.

Check for other possible network services failure

Are your other network services like texting, voice calling, or mobile data affected when the error occurs? If yes, then stop whatever you’re doing and get support from your carrier right away.

Reboot device

If the issue does not appear to be network-related, the first troubleshooting step that you want to do with your Galaxy Note10 is to reboot it. Some minor, odd connection issues are shaken off this way. It’s simple to do and does not require a lot of effort. Try restarting it normally first by pressing the Power button to access the boot menu. Then, select Restart option and see if that works.

Another way to restart the device is by pressing and holding the Volume Down button and the Power key at the same time for 10 seconds or until the device’s screen turns on. This simulates the effect of having disconnected the battery from the device. If this works, this may unlock the device.

If doing the regular restart won’t help, then try this:

  1. Press and hold the Volume Down button first and don’t release it.
  2. While holding it down, press and hold the Power key.
  3. Keep both keys held down for 10 seconds or more.

The second restart procedure tries to simulate the effects of removing the battery pack. On older devices, disconnecting the battery is often an effective way in fixing unresponsive devices. If nothing changed though, proceed to the next suggestions.

Rebooting your device regularly at least once every week can be beneficial. If you tend to forget things, we suggest that you configure your phone to reboot on its own. You can schedule it to do this task by doing these steps:

  1. Open Settings app.
  2. Tap Device Care.
  3. Tap the 3-dot at the top.
  4. Select Auto restart.

Check signal strength

If nothing changes after a reboot, the next step for you is to ensure that problem is not caused by poor or weak signal. This is an important troubleshooting especially if you’re travelling, you’re new to a place, or inside a structure. Your Galaxy Note10 is merely having a hard time trying to connect to your carrier at this time. If the signal bars are weak or keeps disappearing, all you need to do is to wait until you’re back to a good location. If you’re on the move, then simply wait until you reach your destination and see if the situation improves. At this point, there’s no device at all so there’s nothing much that you can do.

Clear network settings

If the signal strength is consistent but issue still shows up, it’s time to reset your Note10’s network configuration. To do that, you’ll want to clear the network settings with these steps:

  1. On the Home screen, tap Apps icon.
  2. Open Settings app.
  3. Tap General management.
  4. Tap Reset.
  5. Tap Reset network settings.
  6. Tap Reset settings to confirm.

Check the SIM

Some connection problems that many people encounter may have something to do with a defective SIM card. Try to ensure that that you check if the SIM card works okay by removing and reinserting it. Make sure that you turn the phone off while you troubleshoot it. While you’re at it, make sure that you wipe the copper contacts of the card with clean, soft cloth. If necessary, replace the old SIM card with a new one. Most carriers will let you do the replacement for free in their store.

Reset app preferences

Some apps and services may not work properly if a default system app is disabled. This can happen from time to time after a system update, or if an app changes system setting without a user knowing. To ensure that all default apps are set to work normally:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your Galaxy Note10 and check for the problem.

Refresh system cache

In some rare cases, Android may encounter all sorts of problems following a major update. In most cases, this is an indication that the system cache may be corrupted. Fortunately, it’s easy to correct the problem. What you can do in this case is to clear the system cache. If your problem occurred after a system update, then follow the steps below to refresh the system cache:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby / Power key.
  3. When the green Android logo displays, release both keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. The Recovery screen menu will now appear. When you see this, release the buttons.
  5. Use the Volume Down button until you are highlighting ‘Wipe cache partition.’
  6. Press the Power button to select ‘Wipe cache partition.’
  7. Use Volume Down to highlight Yes.
  8. Press the Power button to confirm the action to clear the cache.
  9. Wait for a second as the system wipes the cache.
  10. Press the Power button again to reboot the device. This will return the device to the normal interface.
  11. That’s it!

Restart on Safe Mode

If your Galaxy Note10 can’t still seem to open a connection to server at this time, your next move is to see if it’s caused by a bad third party app. This is done by restarting the device to safe mode. While your Note10 runs on safe mode, no third party apps can be launched (they’ll be greyed out). So, if your Android can open a connection to the server, or if the problem goes away while on safe mode, this means that you have a bad third party app problem.

To run your Galaxy Note10 to safe mode:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.
  6. Check for the problem.

If you think that one of the apps is the cause of the problem, you must try to identify it. If you have no idea which one is it, you can use the process of elimination with these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Galaxy Note10 is still problematic, repeat steps 1-4.

Return software to defaults

This is a bit extreme for this type of problem, which may end up being a network issue after all, but factory reset may not be a bad idea if you experience other issues aside from the one we’re talking about here. We won’t recommend a factory reset if the only problem you’re having is this particular issue only so feel free to skip this if you like. However, if you also suffer from other non-related problems like slow performance, viruses, malware, or any other annoyances that you can’t seem to shake off, then go ahead with factory reset.

If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
