[keycloak-dev] Gatekeeper failing to proxy a redirect link

I am using keycloak and gatekeeper to authenticate my web app against Google. Everything seems to work fine, with regular links, but if I redirect the user to a page within my web app gatekeeper exposes the internal URL rather than proxying the data. I'm using the following to redirect the user, via PHP: < ?php header("Location: https://commentcontext.com/protected/dashboard"); ?> But instead of being sent through gatekeeper to that URL it tries to send the user to https://webapp/protected/dashboard which is the internal URL of my webapp and of course webapp doesn't resolve in DNS so it fails. Why is this happening? Is it a known issue? Is there a workaround? Thanks!!! Nick
