Hi, another possible workaround is to add realm public key directly to configuration of your adapter. In that case it doesn't need to be downloaded remotely from Keycloak. Something like this: https://github.com/keycloak/keycloak/blob/master/examples/demo-template/c... You can also try to update to newest 1.1.0.Beta2, which has some additional fixes (or wait for 1.1.0.Final which is going to be released quite soon). Also are there any other errors in server log? Since it returns "status 500" from keycloak server, I would suspect there will be some error in keycloak server log too?
