RemoteCertificateNameMismatch with Certifiacte from my Windows CA

[TobiThreeCX]

Hi there,

I'm trying to integrate on-prem 3CX (v20 RC2, Linux) with an on-prem CRM.
The On-Prem CRM exposes rest services on an IIS via https with basic auth.
The ssl certificate used by IIS was issued by my Domain CA.
All windows domain members trust certificates issued by my CA.

When calling the rest service from 3CX I get the following error:
System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure: RemoteCertificateNameMismatch, RemoteCertificateChainErrors

I think it's because 3CX doesn't know/trust my CA.
How can I make 3CX trusting my CA?

thanks & happy christmas
Tobias

Is 3CX installed on a Windows machine?

No, it's installed on Linux.

I was able to fix the issue with the following links:

• Export a PEM-Format Certificate From a Windows System
• Adding Trusted Root Certificates to the Server
• List all available ssl ca certificates
