"Failed to connect to remote host: <nil>" error log

[jportner]

I recently upgraded my Docker image to use the latest commit on the master branch of Smokescreen (c86310d7000dcb9865fcd25ff3c8455c1603f7fa).

Right after a connection is allowed through the proxy, I'm occasionally seeing this error log message Failed to connect to remote host: <nil> but of course <nil> doesn't contain any helpful information.

It seems like this problem might be related to the recent change in #194? I'm not very experienced with Go but reading the code, I'm not sure how e.Error() is returning nil.
