I see there is a 'snowflake' proxy option in the Tor control panel,
however it gets stuck at 0% and refuses to connect. I can't find any
resources. Closest I found is this forum thread:
https://forum.qubes-os.org/t/snowflake-proxy-causes-crash-in-tor-control-panel/12326
It's not the same issue, but one user does point out that the feature is
broken. The thread is a few months old so this may or may not still be the
case. Either way I tried the solution provided by @tzwcfq but it did not
improve things.
Thank you all for reading
