3CX PBX unreachable after upgrade to V20 U3

[mkunkel]

Hi, I have the same problem as mentionend here: https://www.3cx.com/community/threads/3cx-pbx-unreachable-after-upgrade.130082/
(but i'm not allowed to post there )

System is running on a Windows machine.
Local 3CX login page on port 5001 is reachable, but no further connection possible: Error 502 ??
All 3cx services are quit and cannot be restarted...


THX!!

Thx to @bartjj
He posted the solution in the linked thread:

My problem was resolved after uninstalling 3CX and all C++ redistributables on the server
rebooting the server
and then reinstalling 3CX.
Restoring the backup finished as expected after that, the phones ringing again

Thanks for the help @AndreasPo_3CX and support team.
