I am using wireguard client on GL-MT3000 from last few months and never had problem, last few days I am seeing issue that WG does connect initially but you can able to reach anything and eventually you see below messages:

In another post it is suggested it could be a FW issue but I have checked manually ports being used in the confiiguration it is reachable.

Anyother suggestion why I am seeing this error.

AFAIK, none of these messages are a true issue. Just log noise.

Can you connect to the WG server by using an different device?

@admon : Thanks for ur reply, I suspect the same that there are intermittent problem with the WG Server.

Were you able to get this sorted? I've got the same issue.

What issues?

The original issue is not clear because the log is just normal.
