I have installed BBB 1.0 and enabled it to use a domain.
When I join the demo meeting I receive the following notification:
I have used the following commands to open the ports:
When I check the port status I can see that both ports are listening:
But when I run a check I get this:
What else do I have to configure to avoid this errors?
Thanks in advance for any help.

When I join the demo meeting I receive the following notification:
A firewall is preventing your client from connecting directly on port 1935 to the remote server. Recommend joining a less restrictive network for a more stable connectionI have used the following commands to open the ports:
sudo ufw allow 1935
sudo ufw allow 9123
When I check the port status I can see that both ports are listening:

Going further I have been reading and found that the ports are closed for my domain conferencias.falcorp.net but not for the IP as you can see in the output of nmap:
How can I match the open ports for the domain?

Finally I got it to work.
It was a Cloudffare issue, my domain was configured to use cloudflare an this was blocking the ports.
As I couldn't find how to open the ports in the free account of cloudflare, I just removed it and updated the DNS records of the main domain and afer a few minutes everything is working.

cache/reverse proxy. This is because Cloudflare makes it so the dns
returns the IP address of a Cloudflare server, while the BigBlueButton
client needs to connect directly to the real server.
You can continue to use Cloudflare for other sites on your domain, as
long as you configure the subdomain for your BigBlueButton server as
"DNS Only" - Go do the "DNS" settings in Cloudflare, and click the
cloud icon at the right side. The correct setting for BigBlueButton
looks like a grey cloud with an arrow going around it.
