You need to investigate the http server log output to resolve the issue with the ContentUploadService.
Which command should you use first?
az webapp log
az ams live-output
az monitor activity-log
az container attach
Scenario: Users of the ContentUploadService report that they occasionally see HTTP 502 responses on specific pages.
" 502 bad gateway " and " 503 service unavailable " are common errors in your app hosted in Azure App Service.
Microsoft Azure publicizes each time there is a service interruption or performance degradation.
The az monitor activity-log command manages activity logs.
Note: Troubleshooting can be divided into three distinct tasks, in sequential order:
Observe and monitor application behavior
Collect data
Mitigate the issue
