Hi,

any advise for the following error Quick Play failed for https://xxxduckdns.org/api/tts_proxy/1013501a114d21c9bc9ae553db86329dee1549e5_en-gb_59064dbcb0_amazon_polly.mp3:audio/mpeg({}), however if I remove teh :audio/mpeg({}) portion and end up with Quick Play failed for https://xxxx.duckdns.org/api/tts_proxy/1013501a114d21c9bc9ae553db86329dee1549e5_en-gb_59064dbcb0_amazon_polly.mp3, the audio file is there, I should add if i do noting then the file does play abut 30second after the automation has called? any ideas

Cheers
