Hi everyone our QGC on the laptop is unable to connect with the drone we are not sure since we didn't change anything we verified the voxl px4 config file and the voxl vision

This is the systemctl command I ran to debug my connection

```
voxl:~$ systemctl status -l voxl-vision-px4
● voxl-vision-px4.service - voxl-vision-px4
   Loaded: loaded (/usr/bin/voxl-vision-px4; enabled; vendor preset: enabled)

Couple of questions

1. How are you attempting to connect to the VOXL? Wifi? Radio? etc... Also, what OS are you running (I have heard of firewalls getting in the way of connecting sometimes)? 
2. If you are connecting over wifi, what do you see when you enter the address of the VOXL into a web browser? VOXL-portal is enabled, so if you are truly connected you should see a VOXL webpage pop up
3. Can you please put the output of these commands  here `cat /etc/modalai/voxl-mavlink-server.conf` and `cat /etc/modalai/voxl-vision-px4.conf`
