I have plex (32400 ), wireguard (51820) and swag, nextcloud, organizr and ombi. I used to have a rust game server (28015-28016).
I think the problem started the one time i forgot that i left some ports open to test things, server cpu was at 100% and things stopped working, pulled the power on server and fixed my router settings. It was the same time ubiquiti had a log4j problem so I did a fw reset, update and change pw to router. now only Cloudflare is allowed to connect to 443 that I mapped to 1443 for swag but that was not the case back then.
everything works but I'm worried since I can't get rid off the LD_L1BRARY_PATH thingy.
