Hi there.
I am trying to connect on the DTU servers via Cisco AnnyConnect, but am having some trouble.
I am using the VPN “extra-vpn.ait.dtu.dk” and then using my usual learn/inside login “SXXXXXX” and the then the password i normally use, but this is just resulting in a failed to connect.
I have also tried with other servers like “vpn.at.dtu.dk” but none of them work…
Have you set up multifactor authentication for your DTU account? It’s requirred to use the vpn
For me “vpn.dtu.dk” works
Thanks for the help to everyone, I linked my account with the MS authenticator, and that seemed to solve the issue. 
I also use “vpn.dtu.dk” which has worked for me today.
For the VPN and acces to other on campus resources when working from home the department for IT (AIT) has published a bunch of guides on inside which can be found here: https://www.inside.dtu.dk/en/medarbejder/it-og-telefoni/it-support-og-kontakt/guides/remote
There is a big zero-day incident today related to big-ip vpn. I dont know if that could be related to your issues. DTU might be patching vpns tonight. Many companies are.
