FTB Infinity 3.1.0 Failed to connect to the server

[SirSiman]

Hello,
I have the issue that everytime I try to join my FTN Infinity Evolved Server it fails, with the message: "Failed to connect to the server". I posted the log-file of the client on pastebin. The log-file of the server is in the attachments.

Modpack: FTB Infinity Evolved
Server-Version: 3.1.0
Client-Minecraft Version: 3.1.0
Client-Launcher Version: v1.5.0
Client Java Verion: 1.8.0_231 (16GB RAM allocated, 32GB total)

Latest.log - Server:

It works if I delete the world and play on a new one, but I dont wanna lose everything I worked so hard for (⌣̩̩́_⌣̩̩̀)

I solved the problem by deleting 17000+ files in the data folder of the world!
