Service Bus connections timing out using Java SDK

We're using the Java SDK (version 1.2.8, not deprecated for another year), and experiencing a transport/connection error connecting to service bus: "org.apache.qpid.proton.engine.TransportException: connection aborted"

This has suddenly started happening, in the Northern Europe region, multiple namespaces (the dev namespace as well, which hasn't been used for a while, is similarly affected)

Azure status says the service health is fine; it seems like an API issue as used by the Java SDK. Is there any way we can contact a human, per our developer support agreement?

    Hi @Mark Hepburn,

    You can try updating your Java SDK configuration to use AMQP over WebSockets. This might help fix the TransportException, especially if it is caused by network restrictions or TLS issues.

    ConnectionStringBuilder csb = new ConnectionStringBuilder("ConnecString");
MessagingFactorySettings settings = new MessagingFactorySettings();
settings.setTransportType(TransportType.AMQP_WEB_SOCKETS);
MessagingFactory factory = MessagingFactory.createFromConnectionString(csb, settings);
