The issue was that I was under an incorrect assumption about the whitelisting feature. I whitelisted my server IP that I was using the SDK from, but this was causing the incorrect credentials error. I was simply incorrect in whitelisting my server IP. To anyone having this issue, try debugging without a whitelist of IPs.

I thank MailGun support and definitely David for taking the time to help narrow down such a silly issue on my part. Hopefully this helps anyone else with such an issue - at least to narrow theirs down.
