Can't receive emails from gmail

I saw this post where someone was having this problem, but it seems to have been closed because it’s old.
Hello, I can send and receive all emails except that I can’t receive emails from gmails. I’m getting the following error about email delivery failure from sent email to server.

The response was:
TLS Negotiation failed: FAILED_PRECONDITION: starttls error (71): 94771312888008:error:10000417:SSL routines:OPENSSL_internal:SSLV3_ALERT_ILLEGAL_PARAMETER:third_party/openssl/boringssl/src/ssl/tls_record.cc:594:SSL alert number 47

Please let me know the fix, I’m dying because of it :\

Solution:
This way i solved the problem and can now receive mails from gmail.

On cloudflare please disable proxy for the following DNS record.

  1. Mail
  2. Webmail
  3. Your hostname subdomain, if mail.yourdomain.com is not your server host name

Try sending it this time, it will work.
