 Hello, this morning, in China, Tor Browser 8.5a11 version can't connect to
 Tor network through Snowflake bridge again. At about Beijing Time 10:00
 A.M., in China, Tor Browser 8.5a11 version can connect to Tor network
 through Snowflake bridge. But after a while, Tor Browser 8.5a11 version
 can't connect to Tor network through Snowflake bridge again. "Tor failed
 to establish a Tor network connection. Connected to a Tor relay failed.
 (done - 0.0.3.0:1) " is showed in the connection interface. It seems that
 China's firewall can automatically detect Snowflake proxies and block the
 Snowflake proxies that China's firewall detected.


 Below is Tor log messages.
