Fix/Soution
The URL parameter of the Connect-SPOService cmdlet accepts only the url of SharePoint Online Administration Center site. To work with any of your site using SharePoint Online PowerShell module, you have to first establish a connection with SPO tenant site which is the admin site of your SharePoint tenant in Office 365, once this connection is established you can access any SPOSite using Get-SPOSite cmdlet.
Connect-SPOService -Url https://TenantName-admin.sharepoint.com
Once you connected your Admin site, you can get your required SPO site details using the below command.
Get-SPOSite -Identity https://TenantName.sharepoint.com/sites/SiteName
You can set required details in SPO site using the below command
Set-SPOSite -Identity https://TenantName.sharepoint.com/sites/SiteName -Owner [email protected] -NoWait
