Hello I tried to check the keycloak/examples/broker/google-authentication-sample with Keycloak 6.0.0 and Wildfly 16.0.0. Unfortunately org.keycloak.broker.oidc.AbstractOAuth2IdentityProvider is not able to connect to all google endpoints and fails with timeout. With my "old" system (Keycloak 2.5.5 and Wildfly 10.0.1) on the same machine the correspondig example succeeded. Proxy-settings via -DhttpProxy-Java-runtime-parameters had been done, so this may not be the problem. Interesting(?): I observed that the connection to https://accounts.google.com/o/oauth2/v2/auth done in the same(!) class org.keycloak.broker.oidc.AbstractOAuth2IdentityProvider just before in the performLogin-method in contrast did(!) succeed (google complains when pushing the "g"-login-button when required redirect-setting is not done). Do you have any idea or fix to overcome this error? Best regards, Eduard Matuszak PS: This is the stack-trace of the timeout-exception when AbstractOAuth2IdentityProvider tried to connect to oauth2.googleapis.com: 10:35:49,298 ERROR
