How to fix AnyDesk keeps disconnecting

In terms of simplicity, security, and features, AnyDesk has hit the jackpot when it comes to lag-free desktop sharing, quickly surpassing TeamViewer. If you use it regularly, you must have come across annoying screen freezes or the dreaded disconnection from the AnyDesk network error. Thankfully, you can fix them with a few tweaks and some in-app settings. Follow this guide to find out how.

AnyDesk may suddenly disconnect during a session due to a number of root causes. These include unstable internet connection, blocking issues with Windows Firewall/antivirus software, or incorrect internet protocol settings. These issues may crop up even if you have enabled unattended access on AnyDesk. Thankfully, you can easily fix AnyDesk’s connection issues. 

Before you begin, verify that your desktop meets AnyDesk’s minimum requirements. Next, check that your system is connected to a stable internet connection and logged in with the correct username and password, rather than using the application in guest mode. You can test your connection speed using free online tools like SpeedTest and Fast. 

1. Run AnyDesk as an administrator

Lack of permissions is a common reason why AnyDesk repeatedly disconnects during a screen sharing session. To fix this issue, launch the AnyDesk application with administrative permissions. Doing so gives the application full permissions to modify or use system resources.

Right-click the AnyDesk icon on the desktop and click Run as administrator . Alternatively, you can search for the AnyDesk application in the Windows Search bar and select the Run as administrator option.

3. Next, go to the AnyDesk website to download and install the latest compatible version for your desktop.
4. Launch the downloaded app and click Install AnyDesk to install it on your device.

To fix this, you must manually add exceptions for AnyDesk to allow its use through Windows Firewall and antivirus.

1. Press the Windows key and search for the Control Panel app to open it. Alternatively, press Windows key + R and type control to execute and open the Control Panel app.
2. Click Windows Defender Firewall .
3. Next, click Allow an app or feature through Windows Defender Firewall in the left sidebar .

6. If you use the default Windows Security application for antivirus protection, turn it on.
7. Expand Virus & threat protection in the left sidebar and click Manage settings .
8. Scroll down to the bottom and click on the Add or remove exclusions link.
9. Additionally, click Add exclusion and select the AnyDesk application to exclude it from antivirus scanning.

If manually allowing the AnyDesk application does not work, you can turn off Windows Firewall or disable Windows Defender on your PC for a while.

5. Enable direct connection

By default, AnyDesk uses the direct connection method to create a session tunnel between the local and remote endpoints. This provides fast connection speeds and keeps your session free from unnecessary interruptions and disconnections. Go to AnyDesk application settings to verify that it is enabled. You can also assign a different local port to create a direct connection.

If it doesn’t solve the problem, you can disable it and route your session through AnyDesk’s servers to share your screen. 

1. Open the AnyDesk application and click the four-bar menu in the upper right corner to access settings .
2. Expand Connections in the left sidebar and click Unlock to configure general settings.
3. Make sure Allow direct connections is enabled . You can also specify a custom local port to establish a direct connection with your client.

6. Reset local DNS cache

Corrupted local DNS cache files are another common reason for sudden remote disconnection issues on AnyDesk. You can resolve this issue by executing some terminal commands on your desktop to clear the DNS cache and reset Winsock.

1. Press the Windows key and search for the Command Prompt application to run it with elevated permissions.
2. Execute the following commands in order to delete the corrupted DNS cache file and reset Winsock.
   ipconfig/release
   ipconfig/renew
   ipconfig/flushdns
   nbtstat -r
   netsh int ip Reset log .txt
   netsh Winsock Reset
