Error - Network binding issue

Learn how to fix errors related to network binding issues in Percy

Network binding issues usually indicate a problem with the loopback interface containing an invalid address. Often, the issue is that IPv6 is disabled, but the localhost entry contains an IPv6 address like ::1. So, when the gateway tries to bind to localhost, it receives the IPv6 address and then fails to bind to it, resulting in an error.

Try these solutions to resolve this error:

Solution 1:

Set the Percy server host using these commands:

export PERCY_SERVER_HOST=locahost:5338

set PERCY_SERVER_HOST=locahost:5338

Solution 2:

Check if IPv6 is disabled on your machine, and then enable it.

Solution 3:

Check that the /etc/hosts file contains only valid addresses for localhost. For example, an IPv4-only host might look like this: 127.0.0.1 localhost.

• Try adding ::1 localhost in your /etc/hosts file.
