Wireguard stale - not reconnecting (25.1.11)

[Spoonman2002]

Hi,

came back from holiday to see that my Mullvad VPN (Wireguard) had status "stale".
So I restarted the Wireguard service, still stale.
From there it went to status "offline".
Did an update to OPNsense 25.1.12, rebooted, still VPN offline.
No matter what I do, the Mullvad VPN will not connect.
In my config and hardware NOTHING was changed, it worked perfectly before I went on holiday.

As a test I used the Mullvad iPhone VPN app, it connects instantly to the VPN server that I also use in OPNsense.
Anyone got any suggestions?

quick update:
I deleted the existing Mullvad peer and instance and configured new/fresh ones.
Took me some time (new keys, config file etc) but it works again, for now.
