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.

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