OpnSense loses loopback connectivity every few hours...

[NoOne777]

Hi!

I'm struggling with a strange issue on my OPNsense 22.1.2_1-amd64.

Every few hours OpnSense loses internet connectivity. Every time this happens, there seems to be a problem with the lo0 interface. If I log in the console and ping 127.0.0.1, I get "Can't assign requested address" :(

If I do ifconfig lo0 down / ifconfig lo0 up, issue fixes itself for a few hours.

Could anyone help me troubleshoot this? Thanks

I just "caught" it failing...
