Operation timed out : Wireguard connection issues

Hello,

I'm trying to create a wireguard tunneling with mt6000 as a Wireguard server and ax-1800 as a client.

After I created the configuration in the server without any changes, I've added the file into client.

But after press start in the client, the client maintaning in orange and the server prompt this message :"Operation timed out. Please check the network environment or reboot the device."

I've reseted by factory the client, and start again. But the it is the same issue.

When I check Ethernet 1 I'm seeing :"It have been used as LAN (Local Area Network).You can set it back to WAN (Wide Area Network) in Network Port Management"

Please check How to troubleshoot WireGuard for the most common issues.
