Sbc on Debian with custom FQDN

[mcdublin]

Hi
I moved a system with a custom FQDN from Windows server to Debian and upgraded to ver 16.4.The problem I have is I cannot get an SBC on Debian to work with it.
I copied the certificate from "var/lib/3cxpbx/Bin/nginx/conf/Instance1" to "etc/ssl/certs" on the SBC machine but it says unable to reach 3cx server.
Has anybody any ideas please.

You need to do certificate chaining/stuffing.

Basically, the SSL cert and the intermediate cert need to be present.
For example, if you look here: https://www.ssllabs.com/ssltest/analyze.html?d=famicol.in at additional certificates, you'll see 2


I'm willing to bet on yours - there is only 1.

(no, that's not my domain, I picked one off the recently tested board)
