When installing 3CX v15 you are asked for a location of the SSL to install to your custom FQDN. When I upload my PFX file (which includes my cert, intermediate cert, and private key) it installs the certificate into nginx WITHOUT the intermediate certificate. Because of this, in some browsers it is not trusted. I was able to verify this using SSL Shopper's SSL Checker and it confirms the intermediate is missing. Why is 3CX removing this? It is the EXACT same certificate that I installed in Abyss on v14! Additionally the nginx logs show "ssl_stapling" ignored, issuer certificate not found.
