I published my project's code on development server. Before publishing it, I created a website on IIS it's link 192.168.1.133:601 (localhost)
But on chrome get ERR_UNSAFE_PORT error.
Tried Explorer and Edge browser therefore it works.
Actual Result: On chrome get ERR_UNSAFE_PORT Expected Result: Website works.
After my long researches, I found some port list this is restircted by Google.
Thus, I realized that, my port in the list then I changed the port.
Link is https://chromium.googlesource.com/chromium/src.git/+/refs/heads/master/net/base/port_util.cc
In July 2021, I encountered this problem and most of the standard fixes had already become obsolete (especially the one where you open 'Chrome Properties', since I use a Macbook.)
This is a MacOS-specific workaround, and here are the steps:
First, locate the Chrome icon in your 'Applications' folder, then right-click to select 'Show Package Content'. Double-click, to enter into the sub-folder. Select 'MacOS'. Inside, you'll see the Google Chrome executable. Rename it 'portfix', then open up a terminal.
/Applications/Google\ Chrome.app/Contents/MacOS/portfix --explicitly-allowed-ports={port_you_want_unblocked}
Don't forget to undo all of this when you're done with your tests, as this is a vulnerable way to leave your browser for too long!
In my case I used Port 87 and got the error ERR_UNSAFE_PORT. After changing the Port the site is working...
