Qlik Sense: "The proxy is waiting for a new session" when opening the hub on Central node

[Daniele_Purrone]

Launching the Hub produces the error

The proxy is waiting for a new session 
 

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.

Environment: 

Qlik Sense Enterprise on Windows  

Resolution:

• Restart the Qlik Sense Dispatcher Service
• If the issue persists, restart the server hosting Qlik Sense
• Verify that the C:\ drive of the Qlik Sense server host has not reached critical disk space capacity issues
• Certificates may need to be recreated. See How to recreate or just delete certificates in Qlik Sense - No access to QMC or Hub for details.
