what can it be and how can i fix it

[Player3324]

This looks like it couldn't reach any of our metadata servers, did you try running the installer without an internet connection?

[brawaru]

Are you from Russia by chance?

If so, Russia ¹ is now blocking Cloudflare, Amazon CloudFront and Hetzner ². Unfortunately, Fabric uses Hetzner as a hosting provider for the website and Cloudflare for its CDN, as a result, both are barely functional over there.

Your best bet there is to use a VPN. Alternatively, you can try using a DPI fooling tool like Zapret. Or both, because VPN protocols like WireGuard are blocked there as well.

Footnotes

1. With exceptions to regions like Moscow. ↩

2. They send a random number of bytes and then drop all further packets, resulting in a timeout. ↩

oh, i didnt really think that its related, ty
cant u recommend any good free VPNs?

[brawaru]

Unfortunately, I can't give you a solid recommendation, because what works and what doesn't depends on your internet service provider and how well they implement filtering.

You could give Proton VPN a try. While its website is inaccessible, you can download it directly here. After installing it, click ‘Create account’ to activate a basic VPN connection. This will let you sign up for a Proton account and sign in to the VPN. After that, you'll be able to use Proton VPN normally, for free.

Please note that you can only access Proton websites while the basic connection is active. Close the app to turn it off.

The next installer version will have proxy support: 96bea0e
And more detailed error messages to help dermine when its been blocked: 9e7647f

I dont think there is a lot more we can do at least without going out of our way.
