KpEmail TLS 1.2

[roska]

My Email Provider stopped supporting TLS 1.1 or lower this month, and now I don’t receive any emails.

Im running Scada Mono on a Raspberry Pi, version of the Server is 5.1.3.0, Version of communicator is 5.2.1.0

error message in the line.log is:
2022-06-21 14:04:08 Command to the Device 41 “Email sender”, type: KpEmail
Error sending email to asdf@provider.net: Message could not be sent.

the OS (raspbian) and openssl are up to date and support TLS 1.2 and 1.3

is TLS 1.3. or 1.2 supported in newer versions of Rapid Scada?

As I understand, TLS version depends on the framework version.
Link 1 is about .NET for Windows
Link 2 is about Mono Framework for Linux

What Mono version is installed?
To check, execute
mono --version

Alternatively, consider sending notifications by Telegram messenger.

I had already upgraded to the latest version 6.12.0.182, but it didn’t solve the problem.
I installed the telegram driver, this is working. Thanks for your support.

There is a magic command that I use sometimes to fix SSL issues:
sudo apt-get install --reinstall ca-certificates
