RDP Connection drops over VPN

Hello everyone, can anybody help me with ideas? Both of my computers are Win10 and suddenly I can't use Remote Desktop Connection these days. So I chose to connect with VPN, but it suddenly blacked out and showed reconnect dialog. What's going on?

How to fix “RDP Connection drops over VPN”

In most cases, you’ll need to configure the VPN when you have to use RDP to connect two computers under different networks, for example, remote into your office computer from home. And some users also choose RDP over VPN for security. But what should we do to the issue “RDP Connection drops over VPN"? Here we come up with 3 solutions to help you out. Follow me to have a look.

Fix 1. Check the network connectivity

Sometimes, the issue is related to the network. If the network is in an unstable state, then RDP Connection drops frequently and it even keeps disconnecting over VPN. Therefore, checking the network connectivity is necessary.

Step 1. Search “Settings” in the search box (or press Win + I) and then find Network & internet.

Step 2. The status of your network connection will appear at the top. You can easily figure out whether your network is accessible.

Fix 2. Create RDP Connection without VPN

To check whether the issue is due to RDP or VPN, you can disable VPN for a while and then connect RDP. If you connect successfully, then the issue "RDP Connection drops"  is related to VPN. Disabling it and creating RDP Connection without a VPN seems a good solution.

Step 1. Go to Settings > Network & Internet.

Step 2. Select VPN in the left-side menu.

Step 3. Select the VPN connection you want to disable.

Step 4. Click Remove.

Step 5. Search Remote Desktop Connection in the search box and open it.

Step 6. Enter the IP address and the username, and then select connect.

Fix 3. Disable UDP

According to some users, the issue disappears when they disable the UDP. Since most Internet applications work in TCP protocol, it won’t have any effect on Internet access.

Step 1. Press Win + R and then input “gpedit.msc”, and then press the “Enter” key.

Step 2. Navigate to Computer Configuration > Administration Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client > Turn Off UDP On Client 

Step 3. Double click on “Turn Off UDP On Client” and then tick “Enabled”, and then click on “OK”. After that, "VPN RDP disconnect" would be fixed.
