One reason could be that you have not enabled the application logging or the web server logging for your app service. You can enable these logs by navigating to your app service in the Azure portal, selecting Monitoring > Diagnostic settings, and then choosing the log types and the destination for the logs. For more details, see https://learn.microsoft.com/en-us/azure/app-service/troubleshoot-diagnostic-logs

Another reason could be that you have enabled the local cache option for your app service, which can interfere with the log stream feature. You can disable the local cache option by going to your app service in the Azure portal, selecting Configuration > General settings, and then setting the WEBSITE_LOCAL_CACHE_OPTION to Off. For more information, see Troubleshooting Log Stream data not loading/populating in App Services.

A third reason could be that you have configured a private endpoint or an access restriction for your app service, which can prevent the log stream from being accessed from outside the network. You can either access the log stream from the same network as your app service, or whitelist the IP address of the device you are using to access the log stream.

Hey Mohammed,

Try opening your App Service > App Service logs > turn Application logging (Filesystem) to On.

@Ali, Mohamed
If the log stream is not working for your Azure App Service, there are a few things you can try to troubleshoot the issue:

Make sure that your App Service is running and has not been stopped or deleted. You can check the status of your App Service in the Azure portal. Check if the App Service has logging enabled: Make sure that logging is enabled for your App Service. You can enable logging in the Azure portal by going to your App Service's "App Service logs" settings and selecting the appropriate logging options.
To verify that you are using the correct log stream URL for your App Service, go to the Azure portal and navigate to the "Log stream" settings of your App Service. The log stream URL should match the one you are using.
Check if there are any network issues: Make sure that there are no network issues that are preventing you from accessing the log stream. You can try accessing the log stream from a different network or using a different device to see if the issue persists. see- Troubleshooting Log Stream data not loading/populating in App Services
Check if there are any issues with the App Service's configuration: Make sure that there are no issues with the configuration of your App Service that are preventing the log stream from working. You can check the configuration of your App Service in the Azure portal.

If none of these steps resolve the issue, you can try restarting your App Service, Let us know if issue remains.

What I've found is I can see my logs in the Event Logs (Diagnose and solve problems > Application Event Logs) but not in the Log Streaming. And everything seems to be configured fine.
