Vizalert not working on Tableau 2023.3

[cyberoner1]

Hi,
facing issues with vizalert 2.2.1 on Tableau 2023.3

MainThread - 2024-01-08 09:52:54 - [DEBUG] - send_email - email body: Could not process source viz data from VizAlertsConfig/ScheduledTriggerViews for the following reason:

Invalid regular expression found. Could not evaluate expression '' in the field allowed_from_address. Raw error:

allowed_from_address

I know on 2023.1 this issue was solved by setting the gateway public host. But I have set it up and the issue is still there.
In the Parameter from allowed from address I have set .* for testing

Nevertheless it is not working as expected.

I am using the vizalert.exe

switching back to the old vizalert.exe I have (2.1.1) it is working again with 2023.3
Any idea?

There must be something wrong in the whole System of 2023.3
Subscriptions are not working for me anymore (Ticket open with Tableau)
creating new Vizalerts are not working anymore. I even can´t see them in the Vizalerts log when they proposed to start.
Old ones created are working fine.
