Warning: Failed to verify STUN server

[kmcgrego1307]

I just installed BBB today with wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | sudo bash -s -- -v bionic-240 -s <mydomain>.org -e my_email@gmail.com -g -w

This is a VM (VMware Player) with 8GB RAM and 4 cores, configured to use a bridged vNIC on my local network. I've set up my home router (Netgear Orbi, if it matters) to forward TCP 80 & 443 to the VM, along with UDP ports 16384-32768.

I've got everything configured and working, to the point where I can log in as the administrator and start a session, except when I try to connect the audio I get an ICE 1007 error.

The output of bbb-conf --check is

stunclient --mode basic is fine, of course, and I've tried other stun servers to no avail.

I can confirm that TCP ports 80 and 443 get forwarded to the VM, and I think the UDP ports do too but I don't know of a good test of that.

To test whether UDP connections are going through, see

https://docs.bigbluebutton.org/admin/configure-firewall.html#testing-the-firewall

[kmcgrego1307]

I can confirm that the UDP access works between a server on the internet and my internal VM. The firewall seems to be working correctly.

What should I check next?

I am a university lecturer and I wish to use your BBB. But the installation does not work. Please provide me with the solution.

Hello,

Please, I also encounter this error.

I would like to take the opportunity to point out that I have been unable to access the bbb docs for a month now. No guide link works for me.
