Below are five possible solutions to fix Chrome Remote Desktop “An unknown error has occurred” error.

Solution 1. Verify Your Internet Connection

In order to share your computer or connect to another computer that has been shared with you, it's crucial for both devices to have an active internet connection.

Solution 2. Reinstall the "Chrome Remote Desktop Host"

A potential remedy for resolving the perplexing "An Unknown Error has Occurred" on Chrome Remote Desktop is to undertake the reinstallation of the "Chrome Remote Desktop Host."

To address this, it's advisable to consider a temporary suspension of these applications in order to establish a seamless connection.

Solution 4. Dsiable Windows Firewall
