RTSP error when trying to "speak"

[Near76]

My plugin has been on/off again over the years. Until a few months ago it was working fine, now I get the following errors...using Airplay Expresses with latest FW:

INFO Connection to Kitchen Music (192.168.1.216:7000) failed: Request failed, error RTSP/1.0 403 Forbidden

Any idea what could be wrong? Thank you!
