When I am logged in on my computer in multi-user mode and try to switch back to single user mode to do a back up, this pop up appears;

"There is an error when connecting to the server. Please check your internet connection and try again"

My internet is fine and what server is it trying to connect to ?

We run 2 companies and have 2 sets of data files, this error only occurs on one and not the other and it just started after the update.

I keep my files on my local hard drive, I do not use the cloud service.

It logs me out of the company files and then I have to log back into the company in single user mode in order to do the daily back up, very annoying!

Any ideas of why this is happening?

Thanks!
