Hello Francisco,
Thanks for posting your question in the Microsoft Q&A forum.
To identify the main reason for the failure shown in the screenshot, please follow these steps:
Check the application logs: You can find these logs in Azure Monitoring if your application is hosted there. If your application runs with Docker, you can also check the logs there for any relevant error messages.
Review the log table: Check the dbo.log
table in your database. Most of the error logs are stored there, and you can review the latest entries before the application stopped working.
Additionally, consider that NopCommerce has numerous settings in its admin panel, and it's possible that a user may have made changes or restarted the application, leading to the issue.
