Configure SSL correctly in pfSense captive portal, freeradious

I am looking for a freelancer who can configure SSL correctly in my pfSense captive portal, freeradius. I already have an existing SSL certificate and my captive portal is already set up, it just needs SSL configuration. The ideal candidate for this project should have experience in pfSense captive portal configuration and SSL certificate installation. I am using ubiquity Unifi, and when users are promoted to enter their username and password, we receive the certificate not trusted error due to incorrect configuration.

Preferred Skills and Experience:
- Experience in pfSense captive portal configuration
- Experience in SSL certificate installation
- Knowledge of freeradius
- Excellent communication skills, with a preference for email communication.
