Hi Nick, thanks for the article.

I'm trying to run cypress inside wsl 2, but the command yarn run cy:open always display an error message saying this: (Cypress:23887): Gtk-WARNING *: 17:08:53.243: cannot open display: 172.22.208.1:0.0 Done in 40.56s.*

The $DISPLAY environment variable is already set, and VcXsrv is up and running.

Any idea what is causing that?

Hi Nick, Thank you for the article, I'm so grad that it easy to follow and successfully bring it up.

I got the same issue about 'cannot open display'. Finally, I got solution, I just need to change firewall policy for the VcXsrv to able to working in Public even I am in the home (Private network). Then after that, everything work well.
Open the Control Panel as following
Control Panel\System and Security\Windows Defender Firewall\Allowed apps
and Enable VcXsrv in Public.

I also follow this script but it seem not related to this issue.

Just leave the detail in case someone may experience the same.

Hey!

Apparently, in some distros you have to enable the option called X11Forwarding manually first.

Hope it helps, I had no idea what could cause it so I googled the error.
