[Bug] Cannot open videos and always get 403 errors

[RobertoBiundo]

Describe the bug

Any video that I load in my private invidious instance fails to load with the error message
"The media could not be loaded, either because the server or network failed or because the format is not supported."

Since im running invidious using dockers a docker-compose logs -f shows that all calls to /videoplayback reutrn GET 403.
I have tried removing the entire DB, stopping and restarting the dockers, setting DASH on/off, changing resolution from 720p to medium to small.

The server used to be fine for about a month and I watched videos every morning (1-2 videos). But since a week ago I cannot play anything.
