we have been using PVCS for decades with PB10, and 12. Recently I have upgraded to PB2019 (Universal edition) on Windows 10 machine. I am trying to connect to my existing source control, It connects fine and then a few seconds later it disconnects (the round green Icons turns to + sign on all objects as if the object is unregistered).

the pbscc.log file shows the "connect is established..." but still showing + sign on all objects.

log file entry:

I have also deleted all PBG files and got latest version on target, also tried single PBLs too

but dialogue box never showed list of objects:

I contacted Serena/Microfocus support but are saying they have not changed anything, it's PB.
