Mailcow sending mails, but not receiving ( Using Google Workspace )

lio14cha

Hi,
I have configured my mailcow domain with google workspace domain. I am able to send emails But not receiving.
Mailcow Postfix Logs:
info disconnect from mail.google.com[ip] ehlo=1 starttls=1 commands=2
info lost connection after STARTTLS from mail.google.com[ip]
info Anonymous TLS connection established from mail.google.com[ip]: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)
info TLS SNI mail.mydomain.com from mail.google.com[ip] not matched, using default chain

And I have added my mailserver name in google workspace hosts. But whenever I click on “Test TLS Connection”, I get could not validate mail.mydomain.com even though I have added my wildcard ssl certs.

Can any one help me finding the cause for this.

Thanks
