Hi @AbdulabnanMohammed ,
I assumed that you "created" a survey123 survey on your organization's ArcGIS Online (you're the owner), and you cannot create connection to your organization's ArcGIS Online URL? (https://YOURORG.maps.arcgis.com/)
Would you please let peole know your User Type and User Role your organization's ArcGIS Online?
I also recommend you to use my esri to submit a ticket to Esri, and they can help you resolve this issue.
I don't think it's Microsoft Administration end's of issue...but I could be wrong. It might be your orgnization has really strict rules for users to use specific connector.
Hope you get it resolved soon...
