Troubleshoot

This section details common issues with k6 Studio and how to fix them.

`localhost` requests are not being recorded

The proxy doesn’t capture traffic when sent directly to localhost. To fix that, you can assign a hostname to it and make requests through that name. To do that, modify the hosts file on your system. For example, you can add the following line to your hosts file:

127.0.0.1 myapp

After, if you have an application running on port 8000, you can make requests in your browser at myapp:8000, and they’ll show up in k6 Studio.

“Proxy failed to start” error

If you’re on a Mac, make sure you’re not running the k6 Studio application from the Downloads folder. If that’s the case, close the app, move the application file to the Applications folder, and start the app again.
