E-Mail / Emails not sent

« on: February 20, 2020, 04:26:18 PM »

I have a problem sending emails from CWP, I have the latest version of CWP that is hosted on AWS lighsail, However emails used to be sent without problems but this issue suddenly happened.
Firewall is disabled, all ports are opened for testing but still no success, Here is what i get in logs:
postfix/smtp[24175]: connect to gmail-smtp-in.l.google.com[74.125.71.27]:25: Connection timed out
postfix/smtp[24175]: connect to alt1.gmail-smtp-in.l.google.com[2a00:1450:4010:c03::1b]:25: Network is unreachable

I am out of hints!
Your help is much appreciated.
