(Setup: Qubes 4 + Whonix)

I followed the Whonix wiki's snowflake in setting up Snowflake:

https://www.whonix.org/wiki/Bridges#Snowflake

It was always working before 11-06 and I never had a problem. However after updating snowflake-client and updating Whonix something happened that made stop working. I don't think the problem comes from snowflake-client itself since it works fine with a fresh debian-9 Qubes VM.

Looking at the logs this is where it gets stuck:

[NOTICE] New control connection opened.
[NOTICE] Bootstrapped 2% (conn_done_pt): Connected to pluggable transport
[NOTICE] Bootstrapped 1% (conn_pt): Connecting to pluggable transport
[NOTICE] Tor 0.4.2.7 opening log file.

Edit: It seems this is not just snowflake specific, I tried to use some obfs4 bridges and it didn't work!

Don't know if this is indicative of anything but after I add -log snowflake-client.log -log-to-state-dir at the end of the ClientTransportPlugin snowflake line in /usr/local/etc/torrc.d/50_user.conf I obtain the following error:

So it seems there might be something that terminates the snowflake-client process.

leh6r0 renamed this task from Snowflake stopped working after 11-06-2020 to All pluggable transports stopped working after 11-06-2020 .Jun 23 2020, 8:55 AM

leh6r0 updated the task description. (Show Details)

More useful information from my tests: When I setup obfs4 using the Anon-Connection-Wizard the previous obfs4 that I used worked fine. Unfortunately I can't setup snowflake from it.

Thanks for the report.
