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
