No login possible with Steam Client

Good evening from Germany guys,
I started this game a couple of days ago and played it for 30+ hours now, never having any kind of problem.
I came home today and tried to login - but nothing.
This error message appears:
Failed to connect to server. Server may be down for maintenance. Please try again later.
So well, I had some looks into the forum and a dev told to write what the console says, which would be this:
Version 3.46.0.10810
SFS Version: 1.2.0

Create landing screen.
Initializing world screen
No bootstrap configuration file.
Loading configuration from ch-config.json
Landing screen: set login dialog
Starting Steam login process
IO error during authentication: Error #2032
Ok, not giving up I looked into the forum a bit more and found a topic referring to that error. Well, it says "clear your cache", "use another browser" "bla bla bla". I use Steam and when I try to login via browser it doesn't even know my ingame nickname, so....
Help me please.

 

When I was testing to see if Steam could be logged out of manually, I actually encountered, if not identical, a very similar notice when I moved one of the files out of the game folder.

In other words, it's possible one of your game files got corrupted [perhaps during Steam downloading the files from a game update].

It may be worth uninstalling and reinstalling the game to see if that fixes your errors [though no guarantee that won't affect your ability to regain your account, so please confirm with the devs before doing so].

Also, this seems to be the Steam thread regarding the problem, if you haven't already seen it:

I am having the exact same problem, but I have this game on both my laptop and PC, and it very unlikely both became corrupted at the same time, especially considering I wasn't using either then this when to ****.
