One of my clients has set me with a Sharepoint Administrator account. I can login successfully on my computer. However they have a Windows Server 2016 server for me to use ShareGate on. However I cannot login to the Sharepoint admin centre from that server using Sharegate or IE, however I can login with Chrome on the server.
From both Sharegate (and IE) if I select browser authentication I can enter my username and password, it sends an authentication request to my phone which gets processed, but a message then pops up that sign in failed:
I cant see anything obvious in the event logs, does anyone have any ideas?
