Any one know what's up? Or can direct me to another thread with similar problems?

How do I do a full downgrade including plugins to a previous version?

So this happened when I updated from 23.7.3 to 23.7.9 does anyone have any Idea on what I can do to debug or find out what is failing? Where to start looking?
It's been rock stable up until now :(

Thinking about reverting back to a openVpn setup, but really like wireguard.

Following the guide here, I managed to get it working, but disabling / enabling one rule as well (guess rules needs refresh)
