502 Bad Gateway: Application Failed to Respond is an error description indicating that the target application failed to respond properly to a request. This usually occurs when the service is down, still starting, or experiencing deployment/runtime issues. The message also provides actionable hints for remediation, including checking deployment logs, consulting documentation, and contacting the application owner or support. A Request ID is included to help trace the error in logs.
How to Use and Debug
- Check deployment logs. Look for failures or stack traces around the time of the error.
- Consult Fixing Common Errors docs. Follow the recommended steps for common gateway/app failures.
- Review contact points. Use the Help Station or reach out to the application owner for assistance.
- Retry later. The issue might be temporary if the deployment or hosting platform is recovering.
Disclaimer: If you are the owner, ensure your hosting platform status is healthy and that the application is properly deployed and listening on the correct port.
