Facing issues? View commonly occurring errors

Check the regular culprits

Check if the file is saved correctly and you’ve installed the required packages & libraries installed to run the test. In most cases, searching on Google is helpful.

Authentication errors

If you are facing any authentication errors, you might have not passed or passed incorrect credentials. You can find your Username and Access Key on the Account Settings page. Try running the test again and it should solve your issue!

Behind a proxy?

You might face some connection issues if you are behind a proxy as your network may be blocking traffic to browserstack.com. Just whitelist traffic to *.browserstack.com and you’re all set. If you have a complex network setup, just reach out to our Support team and they’ll work with you to get this working.

After you have successfully run your first test on BrowserStack, try integrating your test suite with BrowserStack
