Let's Encrypt SSL request for myUrl.com did not succeed - exiting about bigbluebutton

Hello @Nyandago

In order to emit a letsencrypt certificate, their server connetcs to your server (in port 80) and check if your server is responding by the link you are trying to emit a certificate.

Given that you said you are behind a firewall, and letscrypt got a timeout, it looks like that your firewall is not forwarding (DNAT) to the correct internal address.

In order to validate it, you can run in your server:

tcpdump -nnn -e port 80

And using a remote computer try to connect to your external IP:

telnet external_ip 80

If firewall is correctly configured, you will see the packtes in tcpdump, but I believe it's not the case, my guess is that you firewall is sending port 80 to another internal host (maybe the IP of the old virtual machine).

Greetings @TiagoJacobs

Thank you so much for the reply,

I had to sit down with the network team, we found our firewall is properly configured. (The old virtual machine was shut down and assigned exact IP to the newly configured physical server).

The URL is reachable but displays not secured http domainName. [When visited gives "500 Internal Server Error
nginx"]

I had to restart the server [ bbb-conf ] I get the following message.

bbb-conf --restart
Restarting BigBlueButton 2.7.3 ...

If your BigBlueButton server is behind a firewall, see FAQ.

Hello @Nyandago - I would recomend you to format this server with a fresh ubuntu 22.04 setup and run the bbb-install command.

If you do it and it still not working, it might be the case to connect your network team with some BBB expert, to debug the exact issue that is happening in your environment.
