Enabling remote access to Keycloak

The standalone Keycloak server runs on the top of a JBoss Wildfly instance and this server doesn't allow accessing it externally by default, for security reasons (it should be only for the administration console, but seems to affect every url in case of Keycloak). It has to be booted with the -b=0.0.0.0 option to enable it.

However, if your Wildfly is running on a remote machine and you try to access your administrative page through the network by it’s IP address or hostname, let’s say, at http://54.94.240.170:8080/, you will probably see a graceful This webpage is not available error, in another words, Wildfly said “No, thanks, I’m not allowing requests from another guys than the ones at my local machine”.
