Can you run with LOG_LEVEL=debug? That should log each request and response being sent. I would like to find out what kind of response they send you. I use Namecheap but I haven't seen this problem so far. I also checked the last time the relevant code was changed was 10 months ago, so I guess it's something that changed on Namecheap's end?

@robyscar and @albydnc you may have skipped the step of creating an A + Dynamic DNS Record. See here: https://www.namecheap.com/support/knowledgebase/article.aspx/43/11/how-do-i-set-up-a-host-for-dynamic-dns/

Sorry that took forever... 88474c8a3a allows to have empty "" IP address returned from Namecheap, and won't error out if this happens.

Although I use Namecheap and never had the problem, so that's a bit odd.

Anyway closing this, but feel free to report if it's still broken.
