When you try to start the lab, the download takes 1 second and the start lab button appears again.

The clab-api.highgarden.cybrary.it failure is the issue.
I would recommend trying a different network connection if one is available to you. Note: If you’re located in a country on the OFAC sanction list, then you will not be able to use the app.
I tried connecting via Germany and the Netherlands, but it didn’t help.
This is the conclusion if you connect via a German proxy

Yeah, using a VPN may also pose problems and isn’t part of our recommended configuration for accessing labs.
Unfortunately, if you’re accessing the site from a country on the OFAC sanction list, there’s not much we can do.
I understand, it’s a pity. 
. There are no ways, as I understand it?
You may want to try an AWS instance or other cloud instance. Spin up a desktop in the US or Europe and do your lab work from that.
Okay, I’ll try. Thanks
