For HTTPS a valid SSL certificate from a well-known Certificate Authority (CA) is needed. Self-signed certificates generally do not work, as clients do not trust them. Certificates from Let’s Encrypt have been known to work. Be aware that older devices may not trust these certificates, as they were established as a CA fairly recently.

Please check W3Techs for a list of well-known certificate authorities based on market share and usage.
