Running into an issue getting Pritunl to work on Chromebooks. Followed the Chrome OS setup guide and everything looks configured correctly, but when I try to sign in, I get this error:

“Authentication certificate rejected by network.”

The same setup works fine on Mac and Windows, so it seems to be specific to Chrome OS.

You need to manually select the certificate in the VPN connection settings.

Yes, I’ve done that, but unfortunately I’m still seeing the same error
