This is the error we are getting when trying to access the QAP portal through external login:

Proxy server is responding with HTTP Code 404 – Not Found at load balancer side. This means file  index.html  is not found on Proxy server 

as per the logs analysis, till Jan 2023 we are getting Backend Web Socket connection, after that there is no open & close connections and Backend web socket connection for any saml request. please see the detailed analysis provided as below:

• In proxy server log file(when it was working) we can see the commands in below sequence :
