    The account may have MFA enabled. Did you try just using Connect-SPOService -Url https://tenantch-admin.sharepoint.com and typing in the credentials in the prompt?

    @yagobert ,

    As AnupamShri said, it is required if the account is using multi-factor authentication: Connect-SPOService -Url https://contoso-admin.sharepoint.com

    In addition, if you connect to SharePoint online admin via PowerShell through a proxy server, run following commands and retry Connect-SPOService 

    $cred = [System.Net.CredentialCache]::DefaultCredentials  
[System.Net.WebRequest]::DefaultWebProxy.Credentials = $cred
