The SANDBOX_NOT_LISTENING error occurs when you are trying to access a Sandbox that is not listening on the requested port. This could happen if the port is malconfigured, or the process running on that port has exited.
SANDBOX_NOT_LISTENING:
Bad Gateway
I'm encountering an error and reviewing the docs at /flg~eyJhbGciOiJIUzI1NiJ9._v7-_v39.f3M12-KAPZCzcefUX_oPWq-I0u4iAhoJCQaxpxor_bI/docs/errors/SANDBOX_NOT_LISTENING to understand what's happening.
Please help me resolve this by:
1. **Suggest the fix**: Analyze my codebase context and propose what needs to be changed to resolve this error
2. **Explain the root cause**: Break down why this error occurred:
- What was the code actually doing vs. what it needed to do?
- What conditions triggered this specific error?
- What misconception or oversight led to this?
3. **Teach the concept**: Help me understand the underlying principle:
- Why does this error exist and what is it protecting me from?
- What's the correct mental model for this concept?
- How does this fit into the broader framework/language design?
4. **Show warning signs**: Help me recognize this pattern in the future:
- What should I look out for that might cause this again?
- Are there similar mistakes I might make in related scenarios?
- What code smells or patterns indicate this issue?
5. **Discuss alternatives**: Explain if there are different valid approaches and their trade-offs
My goal is to fix the immediate issue while building lasting understanding so I can avoid and resolve similar errors independently in the future.
To troubleshoot this error, follow these steps:
- Verify the configured port: Make sure that the
ports field used in Sandbox.create matches the port your application is listening on. Follow the documentation to learn more
- Check the Sandbox history: Navigate to the Sandboxes dashboard, select the one you are accessing, and check the history section to see which commands were run and if any errors occurred
