So, I have a few users at our site who are recieving the attached. I have gone through a fair few posts on this in the last few weeks that have been posted here and Adobe seem to be quite useless with help regarding this and asking the basic things that have already been done and seem to be doing nothing about it? 

I got a user to log into an icognitio mode browser on my device under her account which has the adobe_pro license same as me.

I logged into the web browser on my browser, I was able to E Sign a document perfecetly fine. I then tested in the icognito browser on the users account and it come up with the error E-signing services are temporarily unavailable. Please try again later. This also does not work on the users machine after a full reinstall and adobe clean. I also tried removing the license from the users account and re adding but no luck.

This surley tells me that this is an issue adobe side, I am pretty stuck on where to go next with this one, has anyone had any joy getting this fixed?
