Server :- GL.iNet GL-AXT1800
Client :- GL.iNet GL-AXT1800 (using LAN wire for internet)
VPN :- wireguard client and server
Firmware :- v4.4.6
Issue :-
Server and client are setup in different countries. After 8 days of working successfully VPN connection stopped working. Luckily I had setup a backup server(GL.iNet GL-AXT1800) in another country but want to know why VPN connectivity has stopped working with the other server .
Client ( wireguard VPN) logs :-
