Hi, I am successfully running a test for aerogear-unifiedpush-server-1.2.0-alpha.1 on Wildfly 10 , Java 8 in my office network with perfect access , registration of devices and messaging by using https://my_pub_ip:8443/ag-push. So far so good, now last Monday I set up the same environment (for production purposes) at Amazone EC2 instance and tested it with Self signed keys. I am able to access https://amazone_pub_ip:8443 , it displays me the wildfly index page. The moment I access /ag-push in amazone ec2 instance I get a run time exception as below : 18:16:20,702 ERROR [io.undertow.request] (default task-22) UT005023: Exception handling request to /ag-push/: java.lang.RuntimeException: Unable to resolve realm public key remotely at org.keycloak.adapters.AdapterDeploymentContext.resolveRealmKey(AdapterDeploymentContext.java:136) at org.keycloak.adapters.AdapterDeploymentContext.resolveDeployment(AdapterDeploymentContext.java:85) at org.keycloak.adapters.PreAuthActionsHandler.preflightCors(PreAuthActionsHandler.java:74) at org.keycloak.adapters.PreAuthActionsHandler.handleRequest(PreAuthActionsHandler.java:50) at org.keycloak.adapters.undertow.ServletPreAuthActionsHandler.handleRequest(ServletPreAuthActionsHandler.java:68) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) at io.undertow.servlet.handlers.ServletInitialHandler.handleFirstRequest(ServletInitialHandler.java:284) at io.undertow.servlet.handlers.ServletInitialHandler.dispatchRequest(ServletInitialHandler.java:263) at io.undertow.servlet.handlers.ServletInitialHandler.access$000(ServletInitialHandler.java:81) at io.undertow.servlet.handlers.ServletInitialHandler$1.handleRequest(ServletInitialHandler.java:174) at io.undertow.server.Connectors.executeRootHandler(Connectors.java:202) at io.undertow.server.HttpServerExchange$1.run(HttpServerExchange.java:793) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.net.ConnectException: Connection timed out at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at sun.security.ssl.SSLSocketImpl.connect(SSLSocketImpl.java:668) at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory.java:524) at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory.java:403) at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:177) at org.apache.http.impl.conn.AbstractPoolEntry.open(AbstractPoolEntry.java:144) at org.apache.http.impl.conn.AbstractPooledConnAdapter.open(AbstractPooledConnAdapter.java:131) at org.apache.http.impl.client.DefaultRequestDirector.tryConnect(DefaultRequestDirector.java:611) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:446) at org.apache.http.impl.client.AbstractHttpClient.doExecute(AbstractHttpClient.java:863) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:82) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:106) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:57) at org.keycloak.adapters.AdapterDeploymentContext.resolveRealmKey(AdapterDeploymentContext.java:107) Please share some insight to this issue Thanks.
