Unhandled exception occured.... 505 gateway every time unverum launches

[Noboty]

Unverum will work properly maybe once or twice after a new installation. However, afterwards, I get this every single time. Once this happens, I have trouble doing everything. The search function is the most noticeable, becoming unusable most of the time. As in, trying to search for something does nothing at all. It's not that it can't find anything. It is that is didn't try. Same with renaming mods, which becomes almost impossible. It will maybe work once out of every 10 tries. Maybe being the key word. Both of these make keeping mods organized and keeping track of them in general next to impossible.

What is causing this?

If it matters, I'm on the latest version (2.4.1). However, this has been happening to me for the last few updates. I am also running on windows 11, but this was happening on windows 10 as well, across multiple versions of both. I am currently on the latest version of 11.

I'm on Windows 10 and this has happened to me for at least a year as well. To rename mods I open their folder then rename it manually, and search doesn't work either.
