ristreceiver exits when output url uses 'tun://@'

I have been trying to leverage tunnel mode for rist. The ristreceiver --help says to use tun://@ as the output url but I encounter an error about parsing the output url. I noticed it is triggered by the atleast_one_socket variable being false still after parsing the output urls.

It does work every so often but sometimes I will get this.

sudo ./ristreceiver --tun tun11 -m 0 -i "rist://@0.0.0.0:9995" -o "tun://@" -v 4 -p 1
