[BUG] User Realm discovery failed error on Connect-PnPOnline command in SharePoint 2016 On-Premises

[uttambobalade]

We’ve downloaded the SharePoint Responsive solution from the path - https://github.com/OfficeDev/PnP-Tools/archive/master.zip and ran the PowerShell “Enable-SPResponsiveUI.ps1” on SharePoint 2016 On-Premises server.
We have downloaded the SharePointPnPPowerShell2016 version on the server and ran the PowerShell but we’re getting “User Realm discovery failed error” on the Connect-PnPOnline command.

Please guide us/suggest any recommendations or solutions.

SharePoint Version – SharePoint 2016 On-Premises
OS - Windows

Refer to the previous thread opened in another repo - pnp/powershell#393.

Thank you.

Hi,
Do we need to install a specific version of PnPPowershell to overcome this issue? If need more details about the error then see the attached screenshot

Hi @uttambobalade,

Here the first questions that can help you:

• Do you have a proxy? This kind of error is common when an app is trying to connect through a Proxy but this one is not configured
• The script to deploy the Responsive solution use -Credentials parameter to authenticate the user account. You maybe should use another method. Try Connect-PnPonline with another method (UseWebLogin, SPOManagementShell, etc.). If one of them works, edit the script to use the good method

Hoping this will help you

Hi @Laul0 ,

Thank you for your response but the alternate options were also not worked to authenticate the user account. We do not have Proxy on servers. Please find below the alternate options that we tried with no luck -

1. Connect-PnPOnline -Url
2. Connect-PnPOnline -Url -Credentials (Get-Credential)
3. Connect-PnPOnline -Url -UseWebLogin
4. Connect-PnPOnline -Url -SPOManagementShell
5. Connect-PnPOnline -Url -TransformationOnPrem -CurrentCredential

We got the same error message in all of the above commands.

Thanks.
