HTTPoison.Error :nxdomain in lib/ex_twilio/api.ex:19

[scottswezey]

After upgrading to 0.5.1, Message API calls through ExTwilio are crashing with an error:

HTTPoison.Error :nxdomain in lib/ex_twilio/api.ex:19

I've been tried specifying the API domain in my config files, or leaving it out so the defaults apply. I verified that HTTPoison can connect to the api.twilio.com domain via iex -S mix. All ex_twilio source code I reviewed appears to be correct. Name resolution is working correctly on my testing system inside and out of BEAM.

I can't think of anything else to identify if the issue is local to my system, but wanted to open an issue in case others are finding the same behavior. Feel free to close if you can't reproduce.

Thanks

While far from conclusive, reverting to ex_twilio version 0.5.0 resolved the issue.

I'm getting a similar error when calling Message.all

Although other requests seem to appear to be working fine. For example, I'm able to use the Messages.create/1 method just fine.

@scottswezey @DavidVII I made a PR that I believe fixes this issue. The url generation was basically creating invalid urls
