Hi,

I'm running bbb on my ubuntu 14.04 and having issues starting it. It hangs forever (waiting up to 20 minutes)

bbb-conf --restart
# IP does not match:
# IP from ifconfig: 192.168.122.34

Waiting for BigBlueButton to finish starting up (this may take a minute): .........................................................................................................................................................................................................................................................................

I'm running it on a VM that has only a public IPv6. The VM-host has a public IPv4 but its port 80 and 443 is already in use. I have configured bbb to use a TLS certificate (from letsencrypt). But this issue with the service on port 9123 not coming up happened already before I enabled TLS on bbb.

When I navigate to https://xxx.yyy/bigbluebutton I get the

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<response>
<returncode>SUCCESS</returncode>
<version>0.9</version>
</response>

response. So I guess nginx is working fine.

What could be issue with the service not coming up and what is the provider and where can I check its config files?

Thanks a lot for your help in advance!

P.S. Here the check log:

Hi Gesine,

> # Error: Unable to connect to port 9123 (desktop sharing) on xxx.yyy

You'll need to setup rules that forward 9123 from the VM host to the VM.

If your setting up BigBlueButton to server other computers on your network, you'll need to ensure that port 80 and 443 are not already in use on the host computer in which the BigBlueButton VM is running.

Thanks for your reply.

The VM has a public IPv6 and the domain uses it directly (I'm not using the public IPV4 from the VM-host and therefore I'm also not forwarding traffic between them).

On the VM, the ports 80 and 443 are solely used by BBB (the VM only hosts BBB).

I guess the issue is that the service doesn't start up (here from the VM itself):

Hi Gesine,

Hmm ... check the log files in

/usr/share/red5/logs

for any errors on startup. One way to quickly check for errors is to do

sudo bbb-conf --clean

sudo bbb-conf --debug

the --debug will scan the log files for errors. If --debug does not detect any issues, look through the log files manually for errors.

Regards,... Fred
