Local Area Network Permission

[patryk-sredzinski]

For some devices on in one location users are asked for Local Area Network permission.

The same build does not ask for this permission in other locations or with other devices.
It appears on iOS 18.3.1 in one location.

(was reported by one dev working from office, same device works well on his home WIFI, but not in office WIFI, no VPNs there)

If you deny the permission, we'll receive:

func room(_ room: Room, didFailToConnectWithError error: LiveKitError?)

with error = nil (so we don't exactly know the error)
but room connection will not be established.

And since that, no further calls are working, until you go to Settings > App > switch LocalNetwork to ON

Any updates on this issue?

The popup itself may appear due to a variety of reasons (e.g. using ProcessInfo).

What was the server URL in your case @patryk-sredzinski?

[patryk-sredzinski]

@mohieddinezarif Is working with me and he is experiencing this. Let's try to get some help from him.
I am not allowed to share server URL, but it looks sort of like that:

wss://livekit.dev.api.***.com

Just to add additional information here:

Background (Internet / ISPs):
Previously, I was not experiencing this at my home (only at office).
Now, I started experiencing this at home as well at office. No changes on router, same ISP same connection.
In fact, I have a 2nd connection from different ISP, which I was not experiencing this as well, but I started to do so as well recently. I changed the router to a different brand and I am still experiencing this.

When it's happening:

• Previously, it was happening on iOS 18 on one of my devices (iPhone 13), and it was working normally on another device iPhone X (iOS 16.7) even on WIFI.
• Now, I am also experiencing it on the iPhone X as well.

Mobile Data:

• The above is not happening at all when i am on mobile data. Working good on both iPhone 13 and iPhone X , etc.. and any iOS.
• Even if I connect multiple devices to a single hotspot (3g/4g), and try to make the call, the above mentioned issue is not happening.

It worth noting that previously, I could normally get over this by going to Settings -> Apps -> My App -> turn off / on (couple of times) Access to Local Network and then it will work normally on WIFI. Now, this trick is not solving the issue anymore.

@mohieddinezarif can you attach the logs once you deny the request (debug and above, preferably https://github.com/livekit-examples/swift-example/blob/a7cc1f3e199e27e4996b4973732eb2ad58a88560/Multiplatform/LiveKitExample.swift#L55)?

[mohieddinezarif]

@pblazej for both cases when I accept or deny the request here is the logs (short handed):
`

@mohieddinezarif can you provide the full log including WebSocket and URLs e.g. NSErrorFailingURLStringKey

[pblazej]

@mohieddinezarif are you able to provide the relevant n/w info here? Otherwise, we won't be able to proceed with this particular issue.

[mohieddinezarif]

sorry @pblazej for late reply.
It was related to some configuration. Problem fixed.

Thank you for the support.

[pblazej]

@mohieddinezarif thanks for confirming that, I think it's just related to the n/w path 👍
