Here are a few troubleshooting steps to resolve the AJAX issue in your C# application on IIS:
- Check the AJAX Request URL: ensure that the AJAX URL is correct in the production environment. Sometimes relative URLs behave differently on different environments. If you're using relative paths, try switching to absolute paths.
- Check Server Permissions: verify that the IIS server and application pool have sufficient permissions to access the required resources. This includes file system permissions, database access, or external API access.
- AJAX Timeouts: If requests are timing out in production but working in test/local, there may be a server performance issue or a configuration limiting request execution time.
