Sage 100 2020 Advanced
The customer just received the Paya Desktop update to 2.0.3.1
This installed fine and can verify through the task bar that they are on the updated version
Uninstalled, reinstalled so many times that I think they can do it without looking
No luck
Continue to get the "Cannot communicate" error on a couple of machines ( while others are running just fine )
1. Uninstall/reinstall Paya Desktop - both with the version from the web and from wksetup
2. IT says they have removed anti-virus from the problem machine ( this remains my leading suspect causing the issue; however, AV issues seem to be "silent killers" in that there's no obvious way to verify that some anti-virus / anti-malware running somewhere isn't watching from a hidden location.
3. We only get slightly different results if we run Sage 100 in MAS90 mode. In that case, the Paya Desktop splash screen appears before the error again kicks off.
I've run into this error in the past, and nearly 98% of the time, uninstalling and reinstalling the desktop client solves the issue ( always always always as Administrator).
That's not happening in this case.
Are there any error logs that can be accessed to debug this further? According to the customer --- support cases have been opened with Sage and Paya with no results.
