Yesterday i started up a vanilla server so that my girlfriend and I could play together. It ran fine all day yesterday, and I had no problems firing it up when I needed to. Today however, every time i try to load in my server in game, I seem to get stuck on the "loading terrain" screen, and get slapped with a "disconnected" after a while. Again, it's a vanilla server (although i personally play with sildur's shaders and optifine respectively, although they've never given me trouble with this sort of stuff before) and the version is 1.13.2, Java Edition. Any help would be appreciated
Update: I've tried DynIp, I tried allowing every instance of java through my firewall, I've restarted the client and my laptop, other people are able to join my server, i the owner cannot. It's always the same "timed out" disconnect reason and it always occurs as the terrain is loading. People on the server can see me join the world in the chat and then immediately leave, while I never see the world itself as i remain in the loading terrain screen
Update on update: randomly started working again for a moment, before the problem started up again
