[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:720)

[varshithr]

While trying to add an SMTP server and clicking on Test Connection button in General Settings. I got the following error in Odoo 11 community version.
[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:720)

The connection security option I chose was SSL/TLS.
I was using an elasticemail SMTP server.

Please let me know if there is a workaround or if you need more information. Thanks.

@varshithr is this still an issue? Have you confirmed with Odoo 17? If this is no longer an issue then please close this issue.
