SSH not working while connecting to Wireguard IP address

100

The issue is, ssh to public ip or internal ip is working fine. However, this is not working while ssh to wireguard interface ip.

After some research from the internet, I set all wireguard interface MTU to 1380 (for all servers), then restart wireguard, it works now.
