Threat Modeling first Lab

I need help with my lab and challenge for threat modeling 1.2 and 1.3
I keep receiving this message all the time and tried almost all all.

“Your lab connection encountered an error. Click Reconnect to refresh the page and attempt to reconnect to your lab session.”

Are you getting any errors in the Developer Console? (for Chrome, that’s View > Developer > JavaScript Console)

I would also recommend trying a different network connection, if one is available to you.
