We’ve been asking for an option in the CLI to fail if logged out. It should work well in the GUI too.
The issue seems to be that TVAI checks in if you are connected to the internet. If at that time it fails to connect to the authentication server, it logs out and adds the watermark—But only when it starts a new job. From what I have heard, if you are not connected to the internet, it will not check in and your authentication will last months.
The other night, my internet service provider had their main router die. Their backup router would only route google domain traffic. TVAI watermarked the rest of that jobs it did that night. I would have rather woke up to find errors about being logged out.
