SSL certificate issue causing 3cx web hooks not receiving sms

[roy77kahnman]

i have a enterprise account using a custom fqdn. i'm unable to receive sms through 3cx webhooks and get this error...
The PBX is not reachable via the Internet. Ensure that all necessary ports are open and that the firewall check is successful. The error code received is: UNABLE_TO_VERIFY_LEAF_SIGNATURE

I did some research and add the intermediate certificate to /var/lib/3cxpbx/Bin/nginx/conf/Instance1 and updated /var/lib/3cxpbx/Bin/nginx/conf/nginx.conf to reflect that yet i still have the same problem.

When i do a SSL test from https://www.ssllabs.com/ssltest/ i get Assessment failed: Unable to connect to the server

Yes, for it to work you need to have the intermediate cert as well. Are you sure nginx restarted successfully after the change you made?

Hi @roy77kahnman,

Is a custom FQDN required? Using a 3CX FQDN would most probably resolve this.
Just as suggestion though, not a requirement. If you fix the SSL issue it should work just fine.
