I have a keycloak installed on wildfly standalone. I'm trying to deploy an application, that use this keycloak, on a separate server with wilflly running on domain mode. I tried first to deploy on a domain out of the box on my local machine, setting the keycloak-wildfly-adapter-dist-1.0.4.Final. It deploys fine and does the authentication without any issues. When I try to migrate it to the server running my wilfly (also in domain mode and the keycloak adapter set), it deploys fine and shows the keycloak login once you enter the application. But the problem is that when you login it displays a "403 - Forbidden" and on the log I'm seeing 

ERROR [org.keycloak.adapters.OAuthRequestAuthenticator] (default task-6) failed to turn code into token

ERROR [org.keycloak.adapters.OAuthRequestAuthenticator] (default task-6) status from server: 404

The only difference between those two wildfly domain mode is that in the local I don't have the the SSL/HTTPS enabled.

Have anyone seen this error? or have an idea of what this could be?

Regards
