Voice assistant on IoT network results in crash when getting a reply

Hi all,
I’ve recently made a Onju voice and love it.

Upon moving it to my IoT network i noticed something strange.
Everything when i ask HA a question, the device would restart itself.

Digging into the logs i see the following:

[15:17:25][D][voice_assistant:595]: Response URL: "http://192.168.x.21:8123/api/tts_proxy/a434eb772185c3b7e8b524ee31633d15df71245a_en-us_b75db10870_tts.piper.mp3"

The response URL the onju is getting is from my main trusted vlan.
How can i tell HA / voice that a different IP should be used?
