3cx via FQDN not able to access

[meeas]

Dear team,

I have tried reinstalling and everything i could but i am not able to access the pbx via FQDN.

what i did earlier

i installed 3cx software on a windows 10 operating system and it was accessible and afterward i had a vacant machine so i took the liberty to install Debian based 3cx os. now i can access from ip address but not from the FQDN and also no extension could connect.

secondly, receiving only missed calls on android app while using any random ip. no port has been disturbed during process.

Regards

Have you switch off your old Windows 3CX machine ?

Does the debian machine have the same IP address as the windows machine, if not have you adjusted your firewall rules to point to the debian server

Hi @meeas,

Are you able to resolve the FQDN to the correct IP?

Hi @meeas,

Are you able to resolve the FQDN to the correct IP?

i am using static ip and that ip was same as i did in first and second installation. Different broswer report connection rufused error where i can access it via https://ipaddress:5001

also dns checker report to correct ip address.

If you can't resolve the FQDN, try to restart the System Server.



Once it's back up, click Settings >> License >> Edit >> OK then Refresh License Key Information. Let me know when this has been done.

Hi @meeas,

Is the PBX installed on the same local LAN as the computer that you're trying to access it from?

yes same i am on same lan.

onething more i am observing that even on ip address i was able to connect secure connection but now it is showing unsecured or no certificate.

There is a good chance you won't be able to access your FQDN from the same location. Are you able to access it from a location different to that of your local lan? If yes, then you'd need to look into your firewall settings as they may be preventing hairpin traffic.

For more assistance, feel free to contact a 3CX Partner to assist.

strange thing is now i can access it from any other ip. why i have no idea but not from the same ip.

In this case it does sound like the issue you are experiencing may be connected to loopback (hairpin) traffic being blocked by your network.
