Hi everyone,

I was previously using BBB 2.2 with Ubuntu 16.04.

I reinstalled from scratch Ubuntu 18.04 and BBB 2.3 with the following install script:

wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v bionic-230-2.3.9 -s mydomain.com -e my.email -g

I did not use '-w' option: I have set my own firewall, because I use port 30 for SSH.

I (successfully, hopefully) migrated my former Greenlight database from my BBB 2.2 installation. I also installed Grafana/Prometheus for monitoring and it works fine.

First, I would like to thank the whole BBB team for their work on the install script, which eases life a lot :-D

I would have a few questions, if anyone can help...

1/ what would be the safest way to upgrade minor releases of BBB? I am not sure I understood the documentation correctly, I was planning to use

wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v bionic-230

Would it be ok?

I have a few custom configurations in /etc/bigbluebutton/bbb-web.properties and /etc/bigbluebutton/nginx/monitoring.nginx (for Grafana/Prometheus), I guess they will not be overriden?

2/ I have a very bad connection from where I am now, but anyway I am surprised to often (but not always) get this message when using 'bbb-conf --restart':

Error: Could not connect to the configured hostname/IP address

But 'bbb-conf --check' shows no error and all services are running. I paste the output of 'bbb-conf --check' and my firewall status at the end of this message, in case it helps.

3/ I keep getting "Call failed (reason=IE error) (error 1004)" when trying to join the audio conference. When I installed BBB 2.3 it worked, but now the audio does not work any more and I cannot figure out why :-(

Audio conference from demo.bigbluebutton.org works fine.

My colleagues who have a much better Internet connection than I do not manage to reach the audio port either.

Any help would be much appreciated,

Mélanie

Hi again,

A quick update to my own post...

2/ I have a very bad connection from where I am now, but anyway I am surprised to often (but not always) get this message when using 'bbb-conf --restart':
Error: Could not connect to the configured hostname/IP address
But 'bbb-conf --check' shows no error and all services are running. I paste the output of 'bbb-conf --check' and my firewall status at the end of this message, in case it helps.

I checked bbb-conf script, this error message comes from this test:

if ! curl -sS $PROTOCOL://$BBB_WEB/bigbluebutton/api \| grep -q SUCCESS; then
	echo "# Error: Could not connect to the configured hostname/IP address"
	echo "#"
	echo "# $PROTOCOL://$BBB_WEB/"
	echo "#"
	echo "# If your BigBlueButton server is behind a firewall, see FAQ."
	echo
	fi

But when I try by hand in my browser to go to the URL https://mydomain.com/bigbluebutton/api

I get this:

<response>

<returncode>SUCCESS</returncode>
<version>2.0</version>

</response>

So I don't understand why I'm still getting the error message?🤔

3/ I keep getting "Call failed (reason=IE error) (error 1004)" when trying to join the audio conference. When I installed BBB 2.3 it worked, but now the audio does not work any more and I cannot figure out why :-(

It still does not work, after multiple server reboots and BBB restarts.

I'm seriously considering reinstalling BBB 2.2.x 😭

Best regards

Try disabling your firewall completely for debugging purposes. Also: Try
disabling the whole ipv6 stack on this machine.

Thanks for your answer, I'll try ASAP.

Can you tell me how I can disable IPV6 completely?

Won't this be a problem for iOS users?

Here are some news:

1/ Disabling the firewall (ufw disable) => no success, I still get

' Error: Could not connect to the configured hostname/IP address'

bbb-conf --debug shows the following:

Original Exception (Redis::CannotConnectError): Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)

Following some forum thread I tried to start redis-server by hand (systemctl start redis-server) and ran 'bbb-conf --clean' again. No luck.

2/ I (tentatively) disabled IPv6 support of the Ubuntu server using

sysctl -w net.ipv6.conf.all.disable_ipv6=1

sysctl -w net.ipv6.conf.default.disable_ipv6=1

I removed FreeSWICTH support for IPv6, following https://docs.bigbluebutton.org/support/troubleshooting#Troubleshooting_

and ran 'bbb-conf --clean' again.

Still the same ' Error: Could not connect to the configured hostname/IP address', and no luck with audio ICE 1004 error :-(

I think I will reinstall everything including my Ubuntu 18.04 from scratch :-( because I need to have the server to be in production by the end of this week :-(

But then something is not clear for me: last time I installed BBB 2.3

1/ I used '-a' option to install demo API and everything was fine (audio + video OK and no errors)

2/ I purged demo API and ran the install script again with '-g' option instead of '-a' to install greenlight. Is it the proper way to install greenlight after testing the demo API?

3/ I migrated my old greenlight database (from a former BBB 2.2 installation) to the new greenlight directory and I got the greenlight interface OK, with all the user accounts correct. I followed the procedure described here https://groups.google.com/g/bigbluebutton-setup/c/ssyv7S9eSGw/m/rn5kKwBCCAAJ

But then, after some time, I began to get errors, and the audio failed.

Did I make an error when migrating greenlight database? I'm suspecting an error somewhere, because I have 2 postgres docker images running (9.5, presumably coming from the former BBB 2.2 server, and 13.2-alpine). Did someone fully describe a procedure to migrate a greenlight database from BBB 2.2 to BBB 2.3?

I found this post, do you think it's ok? https://blog.wirelessmoves.com/2021/05/upgrading-to-bbb-v2-3-and-ubuntu-18-04.html

Regards,

Mélanie

Sorry to hear that didn't help.

The different ways to install (-a or -g) cannot be the reason for your
audio problems.

Maybe someone else has an idea what's going wrong there?

Sorry to hear that didn't help.

The different ways to install (-a or -g) cannot be the reason for your
audio problems.

Anyway, if I reinstall everything again, what would be the best way to install greenlight after testing the API demo?

Maybe someone else has an idea what's going wrong there?

I was wondering whether the problem could come from the fact that I don't use '-w' option since I have set my own firewall. But I tested all the ports recommended for BBB installation and they are OK...

Greenlight DB: There is documented how to migrate vom Postgres 9 to
Postgres 13:
https://docs.bigbluebutton.org/greenlight/gl-config.html#upgrading-postgresql-version

Thanks, I'll try that 🙂
