Echec de la connexion Spark sur le serveur Openfire

The following addresses failed: ‘RFC 6120 A/AAAA Endpoint + [beetleheritage.local:5222] (beetleheritage.local/172.20.0.2:5222)’ failed because: java.net.ConnectException: Connection timed out: getsockopt
at org.jivesoftware.smack.SmackException$EndpointConnectionException.from(SmackException.java:334)

This appears to be a networking problem. The computer on which Spark is installed cannot reach the server on which Openfire is installed (which appears to be using the network name ‘beetleheritage.local’).

Check your network configuration, but also things like access control lists/firewalls.
