This is an error or misconfiguration on Salesforce's side - at least it was in my case. You should open a support-case and refer to this link

It would take some time to create domain of the trailhead playground.I would suggest you wait for 5 minutes then log in again to launch the trailhead playground.
Please mark it as solved if my reply was helpful. It will make it available for other as the proper solution.
