Chrome Blocking 10080 leading to ERR_UNSAFE_PORT

If you use port 10080 for web development, you might have experienced issues since many browsers have added it to their ports blocked list.

Right-click the Chrome icon and select properties to add a flag to the startup parameters.

Set the Port parameters to 10080.

NOTE: If your website is currently hosted on port 10080, likely, Google Chrome will not continue accessing it.

Some developers may use port 10080 instead of port 80 for HTTP traffic. It avoids having root privileges to bind Unix systems.

Advice: If your website is hosted on port 10080, it’s probably worth considering using a different port.

Method 2: Initialising Google Chrome

If the above method doesn’t work for you, do a Google Chrome Reset.

  • Hold and Press Windows Key+R and paste the following command inside it:
%USERPROFILE%\AppData\Local\Google\Chrome\User Data
  • Select OK.
Run Window
  • Look for a folder named Default and select it.
  • Do the Shift+Delete combination and proceed by selecting Yes.

ERR_UNSAFE due to Guest Wifi

If Google Chrome denied logging into the Guest wifi due to ERR_UNSAFE_PORT, it would try to access it using a different port. Only in case, your site is currently hosted on port number 10080. It is considered that ERR_UNSAFE due to guest wifi is only because Google has blocked a bunch of port numbers, including 10800.

(Resolved) ERR_SAFE_PORT for Ubuntu/Linux

If you are using Ubuntu, as long as the script is modified as root, it will install the latest version of Google Chrome on your desktop.

Type the following commands in a mannered way:

ls -la /usr/bin | grep chrome

Next, modify the “google-chrome” file appending the mentioned switch to execute it:

exec -a "$0" "$HERE/chrome" "-explicitly-allowed-ports=6000" "$@"

Quickly modify the “6000” port number with the comma-separated port numbers that you might be needed.
