YT bot alert since last night - How can I sign in with MFA?

[leifle]

Describe the bug
Since last night YoutTube seams to think I am a bot and no downloads are possible. In the log of my docker installation I get the following error:
ERROR: [youtube] xxxx: Sign in to confirm you’re not a bot. This helps protect our community. Learn more

As nobody answered yet. I will edit the post on what else I tried just now:

• Just tested the same config on an other server / other IP. And there it seams to work, even though best as the resolution does not with some films. One can live with this.
• So it seams I need to provide YT with a valid cookie or full MFA login. How can this be accomplished?
• My installation is on a headless server. Is there a way to provide the valid cookie through docker volume in a reliable way?

To Reproduce
Steps to reproduce the behavior:

1. Copy URL into the URL filed: https://www.youtube.com/watch?v=OH0GrOaJ0NY
2. Press Download (Selecting resolution does not change anything!)

Expected behavior
Download to start as it did the last year.

Additional context

Is just one example as all the others I tried.
The only thing that changed is that on the server some unused software was removed. But in the docker-compose I can not see that anything uses functions of the host OS, nor can I see that there is a connection to the host OS. No privileged mode or ports via the network are used. Nothing connects to the host network via docker.
The setup is traefik as reverse proxy and that part seams to work fine and was not changed since more then a year.

Basically the question is if there is a way to authenticate towards YouTube. I am a payed YouTube user and don't mind showing who I am. The only reason why I download sometimes is because quite a lot of films I am interested in disappear from YouTube lately, because people close their account or whatever their reasons are.
