Nextcloud Talk not connecting calls

@nebulon said in Nextcloud Talk not connecting calls:

@micmc unfortunately the TURN server on Cloudron cannot run on port 443, which is the most reliable one for webrtc

Yeah, true I always forget this 'limitation' that TURN needs to run on port 443.

We may have to provide a feature to select which TURN server should be used for apps, internal or external, similar to how we deal with email sending.

While being at it that would be a great solution, and for several apps at the same time. +1

@nebulon I just noticed that my custom TURN settings are being overwritten when the app is updated

stun_server
turn_server
TURN server schemes
turn_secret

Looks like signaling_secret is not affected.

I assume this is the expected behaviour but as a user who customises this, I would like my own settings to be honored, please

Where does this come from or where you being sarcastic? (sorry, my translator is not enabled today)

I run my own TURN and STUN servers on port 3478. Maybe I am misunderstanding?

[nebulon]

@3246 this is not a real requirement but just depends on which network the clients are on. Some public wifis for example would block most ports besides the common ones. TURN on 443 is just a safe bet, since 443 is basically always open.

@3246 @girish mentioned public wifis. I think biggest reason for setting up turn on 443 is that very many (most?) academic and corporate IT systems block everything but 443 for ordinary users. So you'll never get a good connection if you have users accessing the internet there.

Cloudron does indeed overwrite the turn server setting in Nextcloud upon reboot/update of the app. Thankfully with Nextcoud you don't need to reboot to add the turnsever back in. So adding it works.

Sadly that's not the case with other apps - notably matrix - which means those apps will be limited in their videoconferencing capability until the ability to add an external turnserver is added to cloudron.

@girish from my perspective I don't think you need a per-app choice there. Just a global option which turnserver to use across apps. My sense is that people who need an external turnserver for one app (because of users in an academic/corporate setting or using Cloudflare, etc) will need it for them all.

@girish @nebulon is there a way for me to hardcode my own TURN server / HPB? I have to manually check and update three Nextcloud sites every day, which is getting a bit tedious

Pretty please

@3246 this is coming in 7.2 - https://forum.cloudron.io/topic/6655/what-s-coming-in-7-2 (the last bullet point)

Amazing! Thank you

@doodlemania2

1. Do I need to install the turn server on the same server I installed the nextcloud

Or a different server?

My nextcloud works fine just that I can not call users on a different network.

How do I do this right, for I call users who are not on the same networks?

Thank you

@girish where are we at with this solution in 7.2? My nextcloud talk won't work with the default turn settings, it only works when all the devices in the call are on the same local network. looks like my preconfigured by cloudron turn settings in nextcloud are on port 3478.

also if i overwrite my turn settings, where in your documentation are the settings located so i can restore to the cloudron defaults?

@dmikolaj is this spam?

[firmansi]

Actually I also still experience this issue, I can't make proper video call even after configure built-in TURN server, is there any port that should be set in firewall ?

[dmikolaj]

@joseph no this is not spam.

I tried both on your demo server and on my own test VPS to get nextcloud talk to work. The calls only work when both callers are on the same network which tells me that the turn server is not working. I also have a hetzner storage share nextcloud instance in which talk works out of the box in the same test scenario.

The hetzner nextcloud talk settings show their turn/stun server configured to port 443 and it works great.

I was wondering if I was doing something wrong, and have been looking through forums to try and see if there is a fix. So far it sounds like the built in cloudron turn server is not on port 443 which means it doesn't work reliably across all networks.

[nebulon]

It is correct, since Cloudron only has one server, where port 443 is occupied by the nginx reverse proxy, the turn server is not running on port 443. This can impact functionality depending on the local network setup. For this you can disable the usage of Cloudron's built-in turn server in nextcloud. See https://docs.cloudron.io/apps/#turn

Afterwards you can configure an alternative turn server, which works in your setup.

[firmansi]

@nebulon I guess the question (which not really provided in docs) is suggested port numbers that should be kept away from firewall

[nebulon]

@firmansi do you mean something like https://docs.cloudron.io/security/#inbound-ports or referring to something else?

[firmansi]

@nebulon yes, thanks

[andreasdueren]

I can heavily recommend running a dedicated turn server or even better the high performance backend for reliable NC Talk conversations. I have had only problems using the built in turn server.

@andreasdueren said in Nextcloud Talk not connecting calls:

the high performance backend

remind me, does that come with a turn server built in?

[andreasdueren]

@jdaviescoates I don't think necessarily, but you can use for example this repo which includes a turn server: https://github.com/sunweaver/nextcloud-high-performance-backend-setup
