Answer 1

Hi @sns
This case is a bit stange and I could not reproduce it, as a workaround, if you are going to connect to a SharePoint Online site, you can use the PnP cmdlet Connect-PnPOnline. For example:

1.Connect-PnPOnline -Url https://contoso.sharepoint.com/sites/yoursitename

Answer 2

Hi @sns
First you could check if this account is a global administrator: Without SharePoint Online global administrator role, it is not feasible to run SharePoint Online management shell, in this case you could refer to:

What's more, you could try using below commands:

$adminUPN="<the full email address of a SharePoint administrator account, example: ******@contosotoycompany.onmicrosoft.com> "  
$orgName="<name of your Office 365 organization, example: contosotoycompany>"  
$userCredential = Get-Credential -UserName $adminUPN -Message "Type the password."  
Connect-SPOService -Url https://$orgName-admin.sharepoint.com  -Credential $userCredential  

which you could refer to:
