Loosing connection

[GIGS1975]

Hello.
When using cast node for playing mp3 on google nest devices, it plays the file correctly, but after it finishes, nodered is looding connection and reconnecting...
This happens only when playing audio file from url, with single text cast this problem doesn't exist.
May I ask, if there is anything I can do about this?
This is how my change node is set up

Thanks in advance
