Problem Forge server.jar running, but fatal error encountered upon launching.

[Vinnskii]

Hello world,

I've been running a FTB Endeavor server with a forge .jar file and portforwarding for about a week now and all of the sudden I've been encountering errors upon attempting to launch the server .jar.

I'm rather inexperienced with running servers, as this was a personal server for my friends and I. I'd just like to know what I could possibly do to save it.

Here is the last part of the .jar log error:

And finally, here is the latest server log: https://gist.github.com/Vinnskii/3d7c8d6330402f69e8bd807a3f8961d1

I have not altered the modlist for Endeavor whatsoever. The items that stick out to a newbie are the "not enough data available", "the handle is invalid" and "exception in server tick loop" lines. Does anyone with experience running servers know a fix to these error lines? Thank you for any possible input!! And please let me know if more information is needed. I'd be happy to grant it!!

How did you create the server - did you use the server installer?

Is this server directly connected to the public internet - if not, then you should remove the ip from server.properties and leave that section blank - even with public facing and only one nic/IP, you should leave that blank.

That is used to bind the traffic to that specific IP if the server have several, but it will not work if the server is behind a router/firewall with the use of portforward.

I used the new FTB official launcher and clicked "download server" from the More<Versions tab. Then I simply ran the serverinstall in a folder as per usual.

Thank you, I will keep that in mind for next time. But the weird thing is that the server worked just fine even with that filled in the server.properties before. Which leads me to believe that there are mod conflicts with the server itself instead of it being an issue with that.

I tried re-downloading the server files, just in case it was an error with those. But it seems like it's an issue with the world file, because I kept the old world file and dropped it into the new server files and got the same error. I don't know if that's something you can do, but I assume you can.
