server.js HTTPS port 12470 has no fallback

At server.js:46862-46867, the HTTPS server binds 12470 with no retry. If occupied, HTTPS silently never comes up. Should have fallback similar to HTTP port.

Verdict: valid.

server.js retries HTTP 11470 through 11474, but HTTPS always calls listen(12470) once and only logs the error event. If 12470 is occupied, the HTTPS endpoint is unavailable while /get-https still assumes an HTTPS server object. Add a port fallback or a clear disabled/error response.
