Hi Dominik, first of all thank you for the first bug report here on Contractor Deck. I've just now tried to connect my Stackoverflow account for my personal account and it worked.
Could you give me more details to what happens when you try to connect it?
I tried to connect using my id (Sipex or ID 1398503) and I get response: Could not integrate the service. Please check if you filled in service username/id (if applicable) and try again later.
I've had a look into your Stackoverflow id and username, but even manually within Stackexchange platform cannot find you. Are you sure this is your user id on Stackoverflow platform?

I thought to come back to your issue, tried to test same user Id you provided. Worked like a charm. Let me know if that works for you.
