hi,
I´m experiencing almost similiar issues since today. I have multiple clients running and non of them can be activated. I did not really changed anything in regards of the settings.
I noticed, that the Dashboard, where all the WG connections are displayed, says "tunnel active:0, inactive: 1" and the switch button at the WG settings can´t be turned on. it stays inactive no matter what.
Is this the same case on your side?
I won´t have the chance to reboot my Unraid and would love to not have to delete and set up the WG config again. And I would really like to know what the trigger for this situation was in general.
