Hello,
I have zerotier running on a tor exit node and recently (~1 week), it has been getting a Cloudflare challenge when I try to run apt updates. Is there a way that tor nodes can be allowed to download from apt?
If you have an account in the Amazon ecosystem, then you might get the desired result by using the cloudflared tool in a backwards fashion.
Past that, if you have a large number of nodes doing this, then use apt-mirror on a node that is not a Tor exit.
