I am getting a "server busy" error on all years (versions) of Proseries. Never had this before.
Not having any other server issues at my office.
Also getting a "Sign in completion error"
Error. "invalid grant"
Description "Token invalid"
Just installed 2021 on my server also
Id reboot the modem and any computers involved and see if anything changes....if youre still stuck in the mud, come back and we'll tag an Intuit engineer
