Can't get track error="wrong response on SETUP"

[Shedoy92]

If you run simultaneous viewing of 54 streams, then for the 55th stream and all subsequent ones go2rtc gives the error “can't get track error=wrong response on SETUP”. What is this error, how to solve it? I need significantly more than 54 simultaneous streams.

Enable trace log level for rtsp module and check SETUP response.

I think the problem is not with go2rtc, but with my NVR. Maybe there is not enough bandwidth.
Checked this by adding streams from another NVR and yes, the streams start without errors.

Well. "500 Internal Server Error". A common error when the camera/NVR is overloaded and can't handle so many clients.
Go2rtc can't do anything about this.
