I have tried adding AE2 1.19 to our modded server, when loading into Single player everything works as it should but after adding it to the servers mod file and connecting to the server there is the same continuous error message.

There is no crash report or anything like that just this. Would this be because of something server side or mod related?

.

Please provide the information requested in the issue template (forced crash report) and in this case, a client-side debug log.

A forced crash report but the issue doesn't create one server sided.

You'll need to provide the client-side debug.log since this is most likely a client-side error.

client-side debug.log
Log as requested.log

Errrrr, the debug log you attached:

1. Shows that you use OptiFine, which we don't support. But I'll ignore that for now since that should not interfere with the server connect.
2. Shows a fatal mod loading error for integratedcrafting
3. Shows no error like the on on your screenshot

   I ran all the mods again and tried connecting to the server, got the same message and these two logs.
   latest.log
   debug.log

Also, I tried loading it without Optifine and I got this error when connecting:

+These two logs;
debug.log
latest.log

I don't see any AE2 related issues in that log. I think you really might have some other issues with your install.

• Reinstall Minecraft / Forge
• Ensure that you have the same mods and same versions on both client and server

Nothing else I can do here, sorry.
