I can't start the lab

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

There are such errors in the console

Access to XMLHttpRequest at ‘https://notify.bugsnag.com/’ from origin ‘https://app.cybrary.it’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.


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. :frowning:. 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
