SMTP Mails from my iDS-7204 HUHI DVR just stopped working via Brevo?

[YasenV]

Hello All,
I have an issue with DVR
Product Type: DVR/NVR

Device Model: iDS-7204HUHI-M1 SA

For 2 years I have it setup sending me emails for different alarms or errors. Suddenly it just stopped working. The configuration is unchaged for a very long time.
I am using brevo smtp and from the same network I have other embbeded device that is sending emails without any issues.

When I use the test button it just says test failed and no more information in the logs. Where I can see more logs, so I can pinpoint the problem?

Regards,
Yasen

Are you using a gmail "app password"? If not then that could be the reason as gmail and most other similar email services have stopped allowing services like this to authenticate with a normal master email password. It may be that your region/account has only recently been changed by Google.

See here:

Tip: App passwords aren’t recommended and are unnecessary in most cases. To help keep your account secure, use "Sign in with Google" to connect apps to your Google Account. An app password is a 16-di

I am not using google smtp but brevo. After playing 3h with the settings, it seems brevo are now allowing non-encrypted traffic to other port. And it worked for me. I guess the TLS on Hikvision and TLS on Brevo are not compatible for some reason. Hikvision does not support 1.3 yet. I can't confirm, but Brevo might be only 1.3
