HTTPS/SEE Connections Ignore TCP Port Numbers in URLs

[moloch--]

Describe the bug The inspector seems to always attempt connecting over port 80 even when the protocol is https: or a specific port number is specified in the HTTPS URL.

To Reproduce Steps to reproduce the behavior:

1. Use an SSE URL such as https://foobar.net/mcp/sse or https://foobar.net:443/mcp/sse

Expected behavior Uses the default protocol port number, or the port number specified in the URL.

Wanted to clarify, are you seeing this issue in CLI mode?

[olaservo]

So far I'm unable to repro this in either the Inspector UI or in CLI mode. Since this issue has been open for a few weeks I'm wondering if this was resolved in a PR since then, or if this is still happening.

[moloch--]

Could have been, I was using the UI at the time, I'll try again.

Closing this since I wasn't able to repro, but please re-open if you're still having this issue.
