HACS HUAWEI Solar Integration - unexpected error with correct credentials

Configuration
1

Hi all
I had some issues with my HUAWEI SUN 2000 and had to reinstall the HUAWEI Solar integration with HACS. Probably the uninstall of the previous integration was not clean enough or correct.
Now when I try to reinstall I have an issue with authentication in the configuration dialog. Connection is fine, when I enter a wrong account it tells me “Authentication failed” what is correct, if I enter the correct account I get a “unexpected error”. So I am stuck with the configuration.

Any ideas what I can try?

Thanks,
Regards,
Mike

here what I can see in the logs, it looks like there is something from my old configuration, but I have no idea how and where to remove.
