Comment (by cohosh):

 Okay upgrade in progress. I updated the snowflake broker and it has been
 running the new version since the timestamp:
 {{{2019/11/13 16:47:02 Starting HTTP-01 listener}}}

 Note that there's a lot of `Invalid data.` log messages due to old polling
 proxies.

 I also updated the four proxy-go instances running on the snowflake
 bridge, so the broker is showing 4 standalone proxies currently running.

 I was able to bootstrap a client connection fully through the newly
 deployed bridge and proxy-go instances. So it seems to be working. I'll
 start the webextension update now.
