SteamServer Disconnected (NoConnection)Solved
I'm running 2 Rust servers on Debian 10 (installed it a month ago, was previously on Debian 9, not sure if this has anything to do with it) and I've recently started having an issue once or twice a day where both servers lose connection to the Steam server and everyone gets kicked. Since it happens on both servers I'm assuming this is an OS/hardware/network problem and not an issue with Oxide, but I was just wondering if anyone else has seen this lately or have any suggestions?

This means your server loses connection to steam or steam servers go down. Maybe it's because of cvirus - probably there's much more traffic than usually. Or your server network issue. And next time consider removing IPs from your messages :)
There doesn't seem to be any post editing option...
There is like an hour or so cooldown, not sure but still small imo. Now you don't have any IPs there :)
For anyone wondering about this in future, I discovered this in the event logs of my router at the exact time of players being kicked. This is either a glitch in my router or possibly a general ISP glitch. Either way, I decided to switch provider anyway (for other reasons).
