Actually I may have stumbled on it just now: https://tomcat.apache.org/tomcat-9.0-doc/web-socket-howto.html "For secure server end points, host name verification is enabled by default. To bypass this verification (not recommended), it is necessary to provide a custom SSLContext via the org.apache.tomcat.websocket.SSL_CONTEXT user property. The custom SSLContext must be configured with a custom TrustManager that extends javax.net.ssl.X509ExtendedTrustManager. The desired verification (or lack of verification) can then be controlled by appropriate implementations of the individual abstract methods." I will try this tomorrow and see how it goes. —Gary >
