Keycloak v18 proxy doesn't work on EKS if you are using [ALB+NGINX]

ok thanks @jangaraj for all your help and advises. I am writing as a reference for others:

I entered there URL because I read something like “KC_HOSTNAME” is the replacement of “KEYCLOAK_FRONTEND_URL” variable in somewhere.

Of course it’s not hard to test it. I tried it as “keycloak.mydomain.com” and also as “keycloak”; nothing changed.

Maybe that’s the same problem:

Thanks & Regards
