Unable to join my own server after update

After the update I’m getting the error that I am not whitelisted on my own server. I’ve tried my local computer IP, public IP, localhost and 127.0.0.1 - which are all added to the whitelist script. All give the same message that I am not whitelisted.

What else could I try?

We do not directly support usermade mods. Might get your info from the one who made it.

Locked.
