My Chromecast is around 6–8 years old. Yesterday everything worked perfectly fine, but today YouTube won’t cast anymore.

Symptoms:

• when I try to cast YouTube, the TV goes black during connecting
• then it disconnects and goes back to the Chromecast home screen
• YouTube stays stuck on “Connecting…”
• tried 3 different phones/devices
• other apps like Netflix/Spotify still cast normally
• Chromecast still appears in Google Home and works

I already tried:

• rebooting Chromecast
• rebooting phones
• clearing YouTube cache
• checking Wi-Fi
• factory reset Chromecast
• setting it up again from scratch

Other apps still cast fine, only YouTube refuses to connect.

Did Google/YouTube recently change something for older Chromecasts? Is anyone else having this issue today or recently?

Is the old Chromecast basically losing compatibility now?
