@rezach98 Please add some more information:

  • Which track are you having trouble with?
  • Which exercise this happens with?
  • What’s your username in Exercism (is it the same here)?
  • Which operating system, browser and version are you using?

Maybe you can also add a screenshot of the hanging online editor / test run.
