So I just made my new TP, found the settings to rename it. clicked on the Launch your hands-on org after making sure it was the default hands on org and I get an error:
This site can’t be reached
cunning-raccoon-380385-dev-ed.lightning.force.com’s server DNS address could not be found.

I have my normal DE org connected as well and it takes me to the login page for that org where I can log in successfully. Not sure what I'm missing?
Any help is appreciated, Thanks!
