What is ERR_UNSAFE_PORT?
ERR_UNSAFE_PORT error occurs when the browser tries to connect to an unencrypted website. By preventing users from accessing sensitive information, Browsers like Chrome, Microsoft Edge, Firefox, etc., can protect you from getting into unsafe connections. Your browser is currently preventing you from accessing the unsafe ports. Attackers can exploit this issue to trick the web browser into performing specific actions that are harmful to the user.
Why does ERR_UNSAFE_PORT error occurs?
This error occurs because the wifi network’s settings have not been set up correctly to allow secure connections.
This issue mainly occurs when data is accessed using a non-recommended port.
Enabling Unsafe Connections
You need to explicitly allow access to the unsafe ports to resolve this issue. There are a few steps that you can follow to get started.

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.
