Obviously the Q-Feeds IP blacklist blocks IPs that belong to the Tor network, therefore a connection is not possible.
Only if you enable the obfs4/Snowflake/meek bridge you can connect again with the Tor Browser. Which is much slower than a normal connection.
Maybe an option "Don't block TOR IPs" would be possible in the options, although it's probably hard to differentiate those IPs from other ones.
