Okay, I asked Deepseek and it immediately pointed out the problem and gived me the solution: the identifier didn't match what the server was expecting. I missed it because I had used a name that was different from the ID... I am sincerely sorry for the inconvenience.
I meant system logs. That's what I would recommend checking.
