Youtube cast to chromecast, stopped working

Casting a youtube video to chromecast, stopped working several weeks ago. (2-3)

The home assistant version is still the same as the one under which casting used to work.

The error in the log claims that the videos cannot be found.
“Could not retrieve data for the URL: https://www.yout…”

playing/casting the same videos through any other platform, works.

Has google changed something?

Found the problem.

had to follow the workaround instructions described here for the same problem which occurred in the past.

the version mentioned there (2019.04.24) is still working. the newest one is the problem
