For now I'm going to pin the version I am hosting to v2,6 instead of latest.

Please share your config, are you using the email field? If so you must set the key field as well. That was previously a bug (AFAIK) not validating the key field (fixed from #702)

Sorry for the delay

{
  "settings": [
    {
      "provider": "cloudflare",
      "zone_identifier": "abc123",
      "domain": "abc123",
      "host": "@",
      "ttl": 600,
      "email": "abc123@gmail.com",
      "token": "abc123",
      "proxied": true
    }
  ]
}

I have the inner part copied 17 times. I have even rebuilt my config file and it still doesn't work on master.

It has been running just fine locked on v2.6 since my previous message last week. So it must be some change between release v2.6 and master branch.

Remove the email key. As per the documentation docs/Cloudflare.md if you set an email, you're also expected to set a key. There is no need to set an email for the other authentication methods.
