Failed to cast media http://homeassistant.local:8123/api/tts_proxy/ac1da9d5f3dd6017afa62cd10e93c56f63a6a9db_en_-_google_translate.mp3 from internal_url (http://homeassistant.local:8123). Please make sure the URL is: Reachable from the cast device and either a publicly resolvable hostname or an IP address


i can’t find the problem

Many thanks

hello, i think you need https or external url.

Google Cast - Home Assistant (

Home Assistant Cast requires your Home Assistant installation to be accessible via https:// . If you’re using Home Assistant Cloud, you don’t need to do anything. Otherwise you must make sure that you have configured the external_url in your configuration.
