acmetool not responding in proxy mode

[jsonnull]

I have acmetool configured via quickstart to run in proxy mode. When I start acmetool, my nginx server access logs show a request from Let's Encrypt for the challenge and the error log is not showing an error, but acmetool hangs and provides no output. How can I find out what's going wrong here?

What does sudo netstat -ntlp show for ports 402, 4402, while acmetool is running?

You can use --xlog.severity=debug to increase debugging output, although there may not be enough debug logging in the right places.

Also, please reproduce this and send SIGQUIT to the process to get a stack trace.

This was probably issue #10, which is now fixed. The fix is in master. I'll push a new release v0.0.11. Let me know if this resolves the issue.
