Inbox not updated automatically in Mail App

[rfx77]

When i am the Inbox in the mail app, new mails do not show up automatically.
I have to press Refresh to get the new mail.

i have the latest version of community-server installed via docker.

in the browser i can see this errors in the console:

i tested with the latest chrome and firefox.

Problem is that the ASC.Socket.IO app.js does not accept self-signed certificates.

i added "NODE_TLS_REJECT_UNAUTHORIZED=0" to get it working
