Hello
I hade a strange problem that made my node offline after I just restarted my computer because of maintenance.
When I started it up again after some hours then it just stood Offline so I thought that its because of my reputation was gone, but after 1 day it still stood offline so I started troubleshooting.
Okey so fast forward to the solution and it was my windows defender who erased?! my custom port filter from the firewall… just by restarting and letting it update itself. So I thought that I would make a topic here and help those who have similar problems…
