Simulation Not Responding
Symptoms
- Requests to simulation URL return timeout or connection errors
- Simulation shows as "running" but doesn't serve traffic
- 502 or 504 errors when hitting the mock URL
Solutions
Verify Simulation Status
- Check the simulation detail page - status should be Running
- If stopped, click Start to activate it
Check the Simulation URL
Ensure you're using the correct URL format:
https://<simulation-id>.srstg.io/<base-path>/<route-path>
Common mistakes:
- Missing the base path
- Using HTTP instead of HTTPS
- Typo in the simulation ID
Verify Route Exists
- Open the simulation and check the routes list
- Ensure a route matches your request's method and path
- Check for path parameter mismatches
Check Request Logs
- Open the simulation detail view
- Go to the Request Log tab
- Look for your request - if it appears with an error, the issue is in route configuration
- If it doesn't appear, the request isn't reaching the simulation
Restart the Simulation
- Stop the simulation
- Wait 5 seconds
- Start it again
Still Not Working?
- Check Route Matching for path matching issues
- Check API: CORS Issues if requests fail from a browser
