Registering Quickbooks Desktop Pro 2021 on Windows 2019 Server gives Gateway 504 time-out
Hi,
I have QB Desktop Pro 2021 installed on a clean install of Windows 2019 (1809) server running on VMware.
Windows has no problems with internet access.
Can access the internet from both Firefox and Internet explorer.
When launching QB from the desktop shortcut, we're presented with the 'begin activation' buton.
We press it and then after a minute or so of a blank white windows form we see:
"504 Gateway Time-out"
What have I tried so far ?
1) Tried first disabling and then removing the Sophos antivirus.
2) Tried switching OFF the firewall
3) Tried adding an outbound rule to allow all programs an outbound connection.
4) Tried different DNS settings.
Should there be a windows firewall rule in place for this to work ?
I have no QB related firewall rules.
Any help appreciated.
Many thanks
