Server crashed and nobody is able to join anymore

Hello,

I have a modded serveur (Forge 1.12.2) running since about a month. I was working well until tonight when it suddenly crashed. Since then, nobody is able to join. Here's the logs:

Thanks in advance for looking at this. I am not too good with errors so I am submiting that to you.
