Launching the Hub produces the error
The Qlik Sense Management Console is reachable and it displays no Engine errors. The Qlik Sense Engine is up and running. This happens on a Central node, and there is no issue with port 4900 (as detailed in article Proxy RIM node error from HUB "the proxy is waiting for a new session).If you have just patched to a more recent version of Qlik Sense, then you may also need to try Recreating the Qlik Sense Root Certificate (Root CA) as NodeJS has newer requirements for the certificate.
