Request Not Processed error when trying to log in.

Hello!
I've run into a strange issue. Until today, everything was fine with Adobe Connect, however, now when I try to open the log in form so I can log in, I get this error.

Do you have any idea why this could be happening? Recently I've been changing who can access the network drive where Adobe Connect stores it's data, could this be the reason? However, it would seem that Adobe Connect has full access to that network drive and the folder where it's shared data is stored. A few months ago my collegue renamed the domain name of our network, but that was a while ago, not sure if that has anything to do with this.
