Suddenly we are unable to login to SharePoint externally to our network.
Internally it works fine.
What could this be?
We had a similar issue at the same time with another server, our ADFS server.
It did the same but wouldn't allow login either on or off network.
I set ADFS to forms-based authentication and it now works but I don't have a root cause.
These must be related to SharePoint, correct??
Thank you for your help in advance!
