My server will no longer allow connections since update

I’ve had a working server since last wipe and everything has been working fine until the wipe. After the update, I updated my server, continuing to update for the patches up to today, and my server will load as usual, but will not accept connections at all. I can’t get my server manager to connect nor can I connect even though I’m on the same computer that it’s hosted on. I have tried removing my server folder and completely reinstalling in with no change in the situation. Any help would be greatly appreciated.
