Can't get web meetings up and running

Hi to all,
I’m stuck at the same point mentioned in this old post:
Since this questioned never was solved, I assume that this problem is hard to comprehend.
To get it to the point, I inserted in my /etc/kopano/webmeetings.cfg:

logfile = /var/log/kopano/webmeetings.log
log_level = 6

but all that is logged is (after service restart)

server 2018/10/01 10:05:26 Got signal 15, stopping all services
server 2018/10/01 10:05:26 Stopped HTTPS server on
server 2018/10/01 10:05:26 Using '/webmeetings/' base base path.
server 2018/10/01 10:05:26.157821 Enabled modules: [roomlocking screensharing youtube presentation]
server 2018/10/01 10:05:26.162299 Using the number of CPU's (1) as GOMAXPROCS
server 2018/10/01 10:05:26.162327 Max open files are 1024
server 2018/10/01 10:05:26.163608 Enabled users handler 'sharedsecret'
server 2018/10/01 10:05:26 Starting HTTP server on

Server and client are in the same network, thus no turn server takes part in the communication.

In Webmeetings.cfg, I set different 32-Byte-Hex-values for session secret, encryption secret and server secret. In presence.cfg another server_secret_ key and brought them together in webapp/config-meetings.php like explains in the web meetings manual.

/var/log/presence.log gives:

2018-10-01 11:13:58,400 - presence - INFO - starting presence
2018-10-01 11:13:58,433 - presence - INFO - spreed: plugin enabled

2018-10-01 11:17:34,059 - presence - DEBUG - spreed: myuser@mydomain available

I tried both, nginx/apache- and apache-only-setup.

So, is there any way to make webmeetings a bit more talkative? And: is there any deeper documentation than this one: ?

Best regards

and which exact error is that?

From your posted logging I do not see an error? What exactly does not work? Which version of the stack are you using (core, webmeetings, webapp, …)?

Hi Felix,
thank you for your reply. The “error” (if any) is, that the camera symbol in webapp stays grey. Further, when I click on the camera-symbol the window stays sort of empty, like shown in the screenshot.

Opening the web meetings webpage directly (not out of webapp) shows the following:

It won’t stop initializing the circle is turning around for ever and ever.

kopano-cli -version says 8.6.80, webapp I installed from webapp- and web meetings from webmeetings-0.29.5_1-Debian_9.0-amd64.tar.gz

So, I don’t really know if that’s an error, but I would expect some functionality for creating a room or something.

Best regards


Ah, he is failing at initialising. In that case you will find further details in the developer tools of your browser (javascript console and in the network tab).

Webdeveloper tools show

SyntaxError: An invalid or illegal string was specified webapp_auth_api.php:191

Honestly, I don’t know what to do with this information. Do you know?

Previous post was the output given on the web meetings page. Webapp gives the following output:

DOMException: "An invalid or illegal string was specified" main.js:43:9383

There was a report in the past here on the forum where a user also wanted to use a mail domain as a username. This is a scenario we do not test for in our tests/which we do not support. Does it make a difference if you use a simple username?

No, unfortunately no difference with “testuser”.

Is there possibly something missing in my php-setup? PHP-Version is

PHP 7.0.30-0+deb9u1 (cli) (built: Jun 14 2018 13:50:25) ( NTS )

Hard to say. I just rolled out a fresh installation with Debian 9 and the current master packages and here everything works out of the box.

I would recommend to get in contact with our support so someone could have a direct look on your system.

Hi Felix,
thank you for your work. Since I’m testing with community edition, is there any possibility to buy support services without subscription?

I’m sure we can make something happen there. Just drop an email to sales at kopano dot com.

Hi Felix,
to bring this topic to an end: because you wrote, that everything is working fine for you, I did a fresh install on another machine and voilà - webmeetings is working and it looks very good :)
So, thank you for your support.
