Hi Freddy,

Does the Indicium log tell any problem?

No, there is no mention in the log file. 

Can you try again but with the Process flow monitor opened? The OAuth login connector should return status code 0 (everything went well). If it's anything else, there must be a problem.

Alternatively, is there a Firewall or something along those lines that blocks the connection the Software Factory is trying to make?

Definitely did not cancel. 

And no, no firewall or something. Because it worked before. 

That is indeed strange. I have created an issue (85057) in TCP for you for this problem. I do think my colleagues over at the Windows team need to look into this.
