Hi, Error 401 is an HTTP status code that indicates an “Unauthorized” access error. This means that the request you are making to your DigitalOcean Droplet is not authorized, which typically happens due to authentication issues based on your PHP application logic. Without seeing any code it is hard to pinpoint the problem, but here are some generic things that you can check: Double-check that the URL you are using in your Android app is correct and pointing to the right endpoint on your server. Check that there are no typos in the URL, including the protocol (http/https), domain, and path. Check your PHP server logs: Access the droplet via SSH : ssh root@your-droplet-ip Check web server logs : Depending on your web server (Apache/Nginx), logs are typically found in: For Apache: /var/log/apache2/error.log For Nginx: /var/log/nginx/error.log tail -f /var/log/apache2/error.log tail -f /var/log/nginx/error.log Look for 401 errors : Review the logs for any 401 Unauthorized errors and note any additional details provided. Review your PHP script/app: Modify your PHP script to log incoming requests and errors. error_log("Request received: " . print_r($_REQUEST, true)); Review the PHP error log for any issues. PHP error log is typically found at /var/log/php_errors.log or specified in php.ini. Go through your PHP authentication mechanism: Check that your Android app is sending the correct authentication credentials. Confirm that your PHP script correctly handles authentication. This would really depend on how you’ve initially set that up. What you could do here is to test your PHP endpoint independently to ensure it works as expected. For example, use curl with the correct method (GET/POST), URL, headers, and body and verify the response and note any errors. You can also add additional logging to capture and inspect incoming request data so you could inspect what might be going wrong. Feel free to share more details about your setup and errors that you are seeing in the logs! - Bobby
