Hi Zach,
Sometimes that lab takes a few minutes to "warm up." We try to stay ahead of demand and pre-stage them, but you could have gotten one that was freshly-deployed and everything hadn't been booted and communicating just yet.
If you could give it another shot and wait about 5 minutes after you login (if you see that same problem with the new deploy), I'd appreciate it. Let us know if you still see issues.
Thanks,
Doug
