Trying to pass {verify, verify_none} showed another error:

=ERROR REPORT==== 22-Sep-2023::16:16:05.580047 ===
    application: mochiweb
    "Accept failed error"
    "{error,{tls_alert,{handshake_failure,\"TLS server: In state start at tls_server_connection_1_3.erl:686 generated SERVER ALERT: Fatal - Handshake Failure\\n unable_to_supply_acceptable_cert\"}}}"

Could be an issue with the how the certificate was generated (has is old signature algorithm). Looking at included server cert with sha1WithRSAEncryption:

% openssl x509 -in ./support/test-materials/test_ssl_cert.pem -text -noout
Certificate:
    Data:
        Version: 3 (0x2)
        Serial Number:
            92:e4:35:9c:c4:44:f2:14
    Signature Algorithm: sha1WithRSAEncryption
        Issuer: CN=localhost

The updated certificate with Signature Algorithm: sha256WithRSAEncryption works. Thanks @etrepum!

I added a script that generates a new self-signed cert which appears to work and will be good for whoever looks at this next so they can see how they were generated. I did get a test failure once but I can't reproduce it locally and it didn't reproduce when I restarted the build 🤷🏻‍♂️

Thank you. That worked. I also noticed the failure afterwards, but It seemed like an unrelated flaky test.
