From Yesterday I’m having issue with name server change :
Issue 1 : Spam Test Result
Couple months everything was fine with mailgun mail server and Cloudflare. But now the mail tester shows " Your DKIM signature is not valid" issue. So, I change name server to namecheap for quick solution.
Issue 2: But couple of hours gone my client knock me that site is not showing. So, I change name server again to Cloudflare.
Issue3: Now my site https://themewinter.com/ not visible from some other country.
Issue4:
Cloudflare diagnosis shows some error but I don’t know how to fix this.
Please, guide me how to solve my issue 1 and issue 4.
