Hi @dianemichel1
Adding to @aman_gup98 , If your ID is missing from Legacy Analytics User management (Admin > Analytics Users and Assets) , can you please ask your System Admin to remove and read your ID in Admin Console and then see if that creates your User ID in Analytics User Management.
In case if your ID is already present, you may want to try connecting without VPN, if possible.
If the issue still persists, I am afraid Support will be the last resort to get this investigated further.
