I made a new thread.
to check if the web interface is working, you could type
pm2 status it should say that UAVcast is running.
If not, then something has gone wrong during the installation.
You can try to start the web interface manually by doing
then start the server
pm2 start process.json --env production
You can also try to start the DroneStart.sh manually to get more verbose output of what is going on.
I have developed a new package UAVcast-Pro which is a more robust application with allot more functions..
It also uses Zerotier VPN which using the NAT traversal technic to gain less lateancy.
it will be out shortly for 19us.
