Hello, 

I've been trying to run mavros from inside a docker container, but it does not seem to be communicating with QGC. I keep getting this error message. Can anybody please tell me what I am doing wrong? Thank you.

@Kiazoa-Joao replace localhost_udp_port_number witih 14551 and then restart voxl-vision-hub service via `systemctl restart voxl-vision-hub` - I am not super familiar with ROS1 and the availability of master IPs and ports, but I believe your ROS_MASTER_IP is correct and your ROS_IP should also be localhost as I am assuming that 192 address is the address of your parent computer.

@Zachary-Lowell-0 thank you. I'll try that and let you know if it works.
