we use WSSO proxy(separate application) which will redirect to the our application deployed in widlfly after validating the user.
we getting the below message intermittently when we tried to access our application and we dont see any error in application log.
Wsso team also saying they dont see any error from their end. They says like my wildfly application server is not responding.
The same server we are using from past 2 years but never face this issue and our other environments working fine without this issue
"Proxy server received an invalid response from upstream server"
Can you please some one help since its impacting our prod.
Thanks in advance
