Cannot renew domain (<domain-name>) on attempt no. 3 certificate: You must set a valid security email address (_APP_EMAIL_CERTIFICATES) to issue an SSL certificate.
what do i need to set value in that env var? please help.
TL;DR
Domain is not being issued an SSL certificate. Set a valid email address in the `_APP_EMAIL_CERTIFICATES` environment variable to resolve the issue. This should be the email where certificates are sent.
