ConnectionError

[JoeSchm]

I uninstalled gdax and reinstalled the latest from github in hopes of better error handling from the API. All I'm really using are the public client and the authenticated client. Now I've had this traceback pretty quickly when I run my trading loops. Anyone know what the cause is or what I could do to avoid? Thanks,

Also, sometime I'm getting the below error. It only happened today. Most of the time there is no issue with this 'price'. THanks

This looks like your DNS is unreliable. If you want automated trading and running over REST APIs, you probably should run a caching DNS forwarder locally, that'll shave off some milliseconds off your requests.

Hey Joe, if you have unreliable connections, I would ensure each packet is returned as expected. I would pass your responses through an if statement to check for expected data and discard the response otherwise. In the meantime, we'll be adding tests and error handling through PR #260 so please follow that thread for updates.
