Task Server always throws 404 in IntelliJ but it is reachable

Hey,

I got a problem with the Task Server in the new IntelliJ Version 2018.1. It always shows me that a request to our task server failed with 404 when I try to select my new task. To solve this I have to go to File>Settings>Tasks>Servers and change the project from "-- from all projects --" to a random project click apply and then change it back to "-- from all projects --" after that the request doesn't fail and I can select my task. After restarting IntelliJ or when i'm changing my project I have to do the same again it's really annoying. We are using Redmine btw if this helps finding the problem. On the old 2017 version I didn't had this problem.
