Answer 1

Hi @Richestsoft , did you view the diagnostic resources? It would help to have a more detailed error message to fix. In the meantime please try the following steps and let me know if they resolve the issue:

1. Check the logs: Access the log files to get more information about the error. You can find the logs in the LogFiles folder, typically located at D:\home\LogFiles.
2. Verify the startup file: Ensure that your web.config file has the correct settings, including the correct path to your main script file and the nodeProcessCommandLine setting.
3. Check for uncaught exceptions: If your application is throwing uncaught exceptions, you can find details in the logging-errors.txt file located in the LogFiles\Application folder.
4. Cold start: If your application takes too long to start, it may result in a 500 error. You can try increasing the values of maxNamedPipeConnectionRetry and namedPipeConnectionRetryDelay settings to prevent iisnode from timing out.
5. Memory consumption: If your application is consuming too much memory, it may affect other processes. You can profile your application for memory leaks or scale up to a larger VM if needed.

Please let me know if you have any questions and I can help you further.

If this answer helps you please mark it as "Verified" so other users can reference it.

Thank you,
