How do I allow ports in Chrome?
To allow sites to access pots such as USB, HID, and Serial Ports, you can configure it from within the Privacy Settings of Chrome. Go to Settings > Privacy and Security> Site Settings > Additional permissions. Then select the port, and configure it accordingly.
Which ports are blocked by Chrome?
Chrome itself does not block any specific ports. However, if a firewall blocks a website or service you are trying to access through Chrome, it may be because it is blocking specific ports required for the website or service to function correctly. If you are using a Mac or Windows, the OS has a dedicated security system that allows you to configure that.
