Unable to access MyCloud Home via Finder

Dear community,

this problem is really getting on my nerves. I’m able to access my Harddrive via the App with the chosen passwords. Whenever I try to log in via Finder, the HD does not accept the same user/password. What am I doing wrong? In order to organize my files with iCloud, I definitely need the Finder.
Thankful for hints!

Best

Have you considered spending a little time looking at the support video as some of the local access functionality has changed.
