Question

After Enabling Extension in Web Apps Windows (Apps Service) website not loading and throwing 503 Error.

Answer 1

Hi @Shyamsundar ,
This problem is often caused by application level issues, such as:

• requests taking a long time
• application using high memory/CPU
• application crashing due to an exception.

Troubleshooting can be divided into three distinct tasks, in sequential order:

• Observe and monitor application behavior
• Collect data
• Mitigate the issue

Scale the app:Scaling up an app involves two related actions: changing your App Service plan to a higher pricing tier, and configuring certain settings after you have switched to the higher pricing tier.

You can check the documentation for specific steps.
