Like most security protocols HTTPS can start failing for all sorts of reasons, but issues with upgraded security seems to be most common.
- For HTTPS to work the certificate (and key) used to sign the TLS (SSL) connection packets must match one of the certs in the cert:\localmachiroot folder. That means that the fingerprint (hash) of the root key must match the signing key.

Here are the steps:
- Create a Certificate Signing Request (CSR).
- Have the CSR signed by the server.
- Get the signed certificate.
- Include the signed certificate in the HTTP request.
- Make sure to put the Self-Signed CA Certificate in the Local Computer's Trusted Root CA store.
Troubleshooting steps in order (do not skip if a certain step is not successful):
- Test with HTTP
- Test with HTTPS (one-way authentication)
- Test with HTTPS (mutual authentication)

One common cause for this issue is a mismatch in TLS levels between the client and server. In general all sites should be (2020-07) set for tls1.1 or higher.
