As a security measure, Chrome doesn’t allow by default to visit any not known web port (eg not 80,443, 8080 etc).
I had to debug site hosted on port 102 so I made the following bat file to fire up Chrome and test the website:
cd "%AppData%\..\Local\Google\Chrome\Application"
chrome.exe --explicitly-allowed-ports=102
Note that AppData lands you to the Roaming profile, while Chrome installs (if you select to install it only on your account) in the Local folder.
Hope this helps.
