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​

  1. Check the simulation detail page - status should be Running
  2. 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​

  1. Open the simulation and check the routes list
  2. Ensure a route matches your request's method and path
  3. Check for path parameter mismatches

Check Request Logs​

  1. Open the simulation detail view
  2. Go to the Request Log tab
  3. Look for your request - if it appears with an error, the issue is in route configuration
  4. If it doesn't appear, the request isn't reaching the simulation

Restart the Simulation​

  1. Stop the simulation
  2. Wait 5 seconds
  3. Start it again
