Crash on connecting to the server

[Matthysse]

Hello! With your mod installed the server works fine, my client too, but I have an error message when trying to connect to the server. There is no log server-side, but there is this message on the log of the client:

Sorry for the long log. I tried removing the mod from the server and I still could't connect, and when I removed it from the client, it worked, so it really comes from Druidcraft.

It looks like you have two different versions of the mod -- one on the client and one on the server. Check to make sure both of them are the latest release.

Channels [druidcraft:network] rejected their server side version number

[Matthysse]

They are the same, I copied my mods from the client to the server without any change

[noobanidus]

Could you try deleting both versions on the client & the server, and try reinstalling Druidcraft? Because there is definitely some sort of mismatch going on.

[Matthysse]

Yep I re-installed on both the server and the client, with only Druidcraft on both (no optifine...) and I have the same problem. Here is the message server-side : https://pastebin.com/4Gr9uJvy the log client-side : https://pastebin.com/Xxx584WN

[noobanidus]

It looks like there's an error on the server-side saying that the advancement list hasn't been loaded. The implication there is that something else is crashing during the start-up phase but the error message is being squashed for some reason.

Can you provide the entire log file from the server?

[Matthysse]

Yes here it is : https://pastebin.com/iKudBzkr

Okay, so, for some reason it's attempting to classload the JEI integration on the server, which is problematic.

Short term solution would be to install JEI on the server as well -- it should have no negative impact on server performance.

Long term solution, I'll try to split it up so it doesn't classload.

[Matthysse]

Okay no problem thanks for the help!

[noobanidus]

While this is technically fixed it isn't released.
