AWS EC2 Server; running only 1 SuiteCRM instance
The inbound emails were working till 2 days back; but now they won’t import the emails. I am using GMail Apps IDs for Bounce Handling; currently there are 8 IDs with unread emails but my SuiteCRM instance won’t process them.
I have already tried deleting all Inbound Emails (Bounce Handling) and creating only 1 account. On the SuiteCRM UI; the connection test is successful; however when I tail the suitecrm logs at debug level; I see the following:

On Gmail Side I have already checked for:
IMAP is enabled
Password is correct
allow less secure is enabled
able to connect to the Gmail account via Outlook using IMAP
imap.gmail.com port 993 Use SSL: yes
Assuming that GMail might be blocking my server to connect for security reasons; I used the commands at https://tewarid.github.io/2011/05/10/access-imap-server-from-the-command-line-using-openssl.html to connect to the GMail account and was able to successfully connect. Herein is the log details:
