webmeetings & ipad/iphone

strippe96

I have just started with webmeetings.
When using a Windows PC everything is working as designed.
When accessing webmeetings by using an iphone/ipad I´ll got the error message:

Your browser does not support WebRTC. No calls possible.

What´s the problem? Safari should be able to run WebRTC, isn´t it?

Hi @strippe96,

the old spreed based webmeetings comes from a time, where iOS indeed did not yet support WebRTC connections. The project the software is based on has not been updated to reflect this.

From our side Webmeetings has been superseded by Kopano Meet, which now with the iOS 13.4 update now fully works on that platform as well (before Apple was declining camera/microhpone access for PWAs).

I encourage to try out Meet.

@fbartels Hi Felix, thank to answere.
I have switched to meet.
User based assess is working as designed.
When I invite a guest he got the error message “Failed to create guest session”.
What´s wrong here?

fbartels

@strippe96 there should be a more actionable error message in the logging of kwmserver (maybe konnect). But it sounds like something is missing in your configuration.

If you have a subscription I would recommend to get in contact with our support, so they can have a direct look at your system.

@fbartels Everything except 1 issue seems to be fine now:

kopano-konnectd[22833]: Error: failed to create client registry: yaml: line 19: did not find expected key

threw this error. How is the way to correct this?

Thanks in advance

Hi @strippe96,

can you share some details about your environment?

What os are you using?
How have you installed Konnect?
How are you running it?

strippe96

@fbartels
It´s an UCS 4.4.4 System.
Konnect has been installed during Kopano Meet install.
Then I have applied your way to enable “Guest access” for Kopano Meet.
At this point the error raised.

Is there a way to clear the whole config of Konnect & Kopano Meet?

Can you elaborate on that?

Which version of the app are you using?

The log line looks a bit like konnect was started through systemd, while with the meet app on ucs everything is running on Docker containers.

I have previously created https://wiki.z-hub.io/display/K4U/Debugging+Kopano+on+Univention#DebuggingKopanoonUnivention-Containerisedapps the collect commands that help troubleshooting ucs installations.

@fbartels OK.

Konnect fails to start, thus you get the 503 later.

This seems strange as the .yaml file contains JSON. That is most likely the reason for the error above. As of how it came to be that way i cannot say. Make sure the identifier registration file actually contains YAML and it will probably just work.

While the first part is true, the second conclusion in the context of ucs is wrong. This is why I asked:

Can you elaborate on that?

The Konnect that is installed as the “OpenID Connect Provider” app is failing, the Konnect that is part of the Meet app is ok (its listed as “healthy” in the ps output).

Yaml is a superset of Json, so what can process YAML almost always can process Json. Konnect most definitely can for the identifier registry.

My theory is that you added the guest registration by hand to the file (and picked the wrong one). To enable the Meet guest mode you only need to say so in the Meet app settings. No manual file editing is necessary.

@fbartels
I changed the config as described @ https://documentation.kopano.io/kopano_meet_manual/KopanoMeet.pdf chapter 3.2.
That resulted in the error shown.

I have found a solution. I deinstalled kopano-meet and OpenID and removed the config files.
After reinstalling both the error has gone.

Now I can use kopano-meet using Edge/Mozilla/Opera on a Windows PC.
Using an iPhone/iPad will result in a screen with the kopano-meet logo and a button with “Anmelden” without any function. No fields for credentials is shown.
IN both ways guest access will result in: Failed to create guest session" after entering a nickname.

@strippe96
I have solved all issues by myself.
1.) Turn all settings in /etc/kopano/docker/konnectd-identifier-registration.yaml from private to public URL´s
2.) Change in “/etc/kopano/konnectd.cfg”: allow_client_guests=yes

Thanks for any help and stay healthy!

fbartels

@strippe96 you don’t seem to be reading what I am writing at all. The linked manual does not apply to the univention app. All you need to do there is go into the app settings in the app center and change a few fields.

There everything is already prepared for you. You can toggle a switch to enable guests and have fields to change the domain name.

@fbartels Dear Felix, sorry for the trouble I have produced yesterday! It has become a worst endig. We have got the information that my wife and me has become a covit-19 infection. Better I have left my server untouched…

Sorry again and stay healthy.

Again, thank you !

fbartels

@strippe96 then i sincerely hope the both of you are getting better soon.

While the german health system feels quite broken at time, from am outside view it seems to perform quite well at the moment.
