3133984 - Error: Proxy Timeout and Failed Requests with 502 Response Code

Symptom

While executing an ImpEx in HAC, accessing an Website/Storefront or Backoffice an error screen with below message appears:

  • 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

In other scenarios, in Dynatrace you can see requests with response code 502 traces failing around a specific time (e.g.: 1 minute, 10 minutes) and when checking the logs at the same timeframe, the following can be found:

  • [proxy_http:error] [pid 144717:tid 139768065645368] (70007)The timeout specified has expired: [client 44.201.212.46:52692] AH01102: error reading status line from remote server xx.xx.xx.xx:8081
  • [proxy:error] [pid 144717:tid 139768065645368] [client 44.201.212.46:52692] AH00898: Error reading from remote server returned by /rest/v2/xxx/xxx
