The domain isn’t verified in Mailgun because the DKIM record that we provided isn’t present in the DNS. I added the TXT record for “krs._domainkey” in Cloudflare and MAilGun says its have to reach out to your domain host for further assistance as it is Cloudflare’s responsibility to propagate DNS records added into their interface into the DNS.
The Mailgun image indicates that it is looking for krs._domainkey.mg and you added krs._domainkey. If you use the matching name, Mailgun should find it. Remember that negative results can be cached. This means that once you have the correct record in place, you may need to wait for a query cache to expire at Mailgun.
Thank you! It finally worked. You know more than both MailGun and Cloudflare support after 2 full days of back and forth. I’m not sure how the last domain even worked.
