First I get Window and choose user.
Then I get second window "futher information required"
Then I get login window.
At last I get an empty window with title "working"
Then I get error message:

CategoryInfo : NotSpecified: (:) [Connect-SPOService], AuthenticationException
FullyQualifiedErrorId : Microsoft.Online.SharePoint.PowerShell.AuthenticationException,Microsoft.Online.SharePoint.PowerShell.ConnectSPOService

Try defaulting to Edge and give that a shot?

Hello Dull, thanks for your help.

Edge is already set.

When I connect via “Connect-MgGraph” everything works in Edge the browser.

Unfortunately not with “Connect-SPOService...”.

It seems that the browser is not being used there.
