TURN server not available

[moan0s]

I wanted to install a TURN server with the script. I executed
wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -c turn.hyteck.de:notsosecret -e certbot@hyteck.de
on a fresh installed Ubuntu 18.04 V-Server from Strato as root.

The process finished with

# This TURN server is ready.  To configure your BigBlueButton server to use this TURN server, 
# add the option

But when I want to check if the TURN server is working I get nothing (also there seems to be no process running).

My BBB-installation does not use this TURN server correctly.

This is how I check if the TURN server is working (as TURN also shuld implement STUN in my understanding?):

$ stun turn.hyteck.de
STUN client version 0.97
Primary: Blocked or could not reach STUN server	
Return value is 0x00001c

I am looking for any advice on how to debug this.

Please feel also free to check the server with the given credentials.

PS: Additional information:

UFW is not (yet) installed

This is the log of journalctl -xe after systemctl restart coturn

Manually starting the server fails too:
The log says:

Maybe you should realize that the turn server can't run on the same machine as the BBB server?

As described in the issue I tried to install coturn on a fresh ubuntu 18.04 server. There was nothing else installed on this server (so also no BBB server)
The only thing I changed was the support of IPv6 that was missing:
New log of a manual coturn start is here: https://pastebin.com/YZ4TZbgT

I recommend that you shouldn't just copy stuff, instead use a REAL/dedicated TURN server.
This can be achieved as shown on the docs page (not like you did...)
https://docs.bigbluebutton.org/2.2/setup-turn-server.html#setup-a-turn-server

The bbb-install script offers the option to set up a TURN server. What I try to do is to report an issue, that this does not work for me. I hope to improve the bbb-install script by reporting this and describing what my problems are.
Of course I work with other solutions to set up a (co-)turn server and I already did that. But that is not the point of the issue.

Hi @moan0s,

I am having the same problem. Did you manage to solve it.

Thanks,

Fresh server instances from hosters often have a web server like Apache httpd or Nginx preinstalled. The easiest way to check is to issue a

$ netstat -eanp --ip

and look, if TCP ports 80 and/or 443 are already occupied by another process.

The current version of the install script already has a check for Apache2 built in, but it fails for other web servers.

Hi I did not solve it sadly and do not run a turn (or BBB) server anymore. Sorry. As I will not be providing any feedback I will close this issue
