Protocol fallback sends HTTP to HTTPS port (443) causing 400 errors #2335
Description
httpx version:
latest
Current Behavior:
When httpx falls back from HTTPS to HTTP on targets with explicit port 443, it keeps the same port, causing 400 The plain HTTP request was sent to HTTPS port errors, i.e resulted as valid / open host but it's actually not.
Expected Behavior:
Before:
$ echo "1.117.60.202:443" | httpx -probe
http://1.117.60.202:443 [FAILED] # 400 error - HTTP to HTTPS port
After:
$ echo "1.117.60.202:443" | httpx -probe
http://1.117.60.202:80 [SUCCESS] # Falls back to correct port
Steps To Reproduce:
echo 1.117.60.202:443 | httpx -silent -title
http://1.117.60.202:443 [400 The plain HTTP request was sent to HTTPS port]
