Comment (by cohosh):

 I started running a new proxy-go instance on a different server. It took
 me a few tries in order to get it as a snowflake from the VPS, but when I
 eventually did, the connection was successful.

 I'm going to say that this a proxy blocking problem and what we need is:

 1. New, unblocked proxies
 2. Something better on the client side than the 30 second timeout to
 figure out that the connection has been blocked we need a different proxy
 (I'll add these notes to #25429).
 3. Some way at the broker to hand out proxies in a smarter way so that we
 aren't repeatedly giving clients snowflakes that are blocked in their
 region
