Hi,

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /order-tests/individual-test.

Reason: Error reading from remote server

we have two bakend server and two frontend server for web server.
After restarting httpd service, it's working some time but again same error appears.
