Scenario 1:

The following error page can be seen

Proxy Error
The proxy server received an invalid response from an upstream server
The proxy server could not handle the request
Reason: Error reading from remote server

This can happen:

• While executing Impex in HAC
• When accessing the store
• When accessing Backoffice

In Dynatrace you can see those failed 502 traces have long response time > 1min

when checking the log you see the error similar to:
