[solved] FreePBX 15 "no server suitable for synchronization found"

FreePBX System Administration

Thanks for the reply, but even if the ISP were blocking
that port, I should still be able to turn on synchronization (which is
not in my subject, I now realize).

I don’t think the ISP is blocking it as I get the same results from my workstation at home.

telnet 173.0.48.220 123
Trying 173.0.48.220...
telnet: connect to address 173.0.48.220: Connection refused
