Is there a reason you are not using the Connect-ExchangeOnline commandlet?

Connect-ExchangeOnline -UserPrincipalName ******@contoso.com

Hi @Roger Roger

It seems you are trying to use basic authentication to connect to EXO powershell.
Please note that basic authentication is a less secure authentication method and is suggested to be turned-off in your Microsoft 365 tenants.

As DimitriS suggested, please consider using modern auth to connect to EXO powershell.
