My Android app doesn’t connect to the server as soon as I am in my home wifi, which is a standard vodafone cable internet router. If I switch wifi off it works, on other wifi networks it works as well. Any idea what would cause this?

Deactivating the firewall in the router does not change the issue.

IPv6 possibly? I believe AndroidOS prefers v6 and if there’s an issue falling back to v4…

The only IPv6 related setting in the router is “IPv6 host exposure”. I don’t think that’s what I want or need for this issue.  
Is there a way to see logs or something which will help narrow down the issue?

Try:

Requirements:

- For browser tabs: Android 4.0+ and Chrome for Android
- A USB cable to plug in your Android device
- Chrome 32 or later installed on your development machine

Set up:

- Enable USB debugging on your device.
- Navigate to `chrome://inspect/#devices` on your desktop Chrome browser. (Alternatively, to get to the same screen, you can select `Chrome menu > Tools > Inspect Devices`)
- After connecting, you may see an alert on the device requesting permission for USB debugging from your computer. Tap **OK**
- Chrome should now display the connected device
- Open up chrome on your Android device and navigate to the page you want to debug/inspect. The page should show up on your desktop browser and you should be able to inspect it.

But: Mattermost in the browser works fine, it’s the App which doesn’t work on the wifi. What would debugging Chrome on the phone help where there is no issue?

You’d be retrieving the logs from the phone.

I don’t undestand how. Did you paste the wrong instructions?

> Open up chrome on your Android device and navigate to the page you want to debug/inspect. The page should show up on your desktop browser and you should be able to inspect it.

This will not help me debugging the app and I can’t retrieve logs from apps this way.

I hope this helps: Installed `adb` on the desktop. Connected and allowed USB-debugging on phone. ran `adb shell ps | grep "mattermost"` to find out process name is called `com.mattermost.rn`. Then ran `adb logcat | grep com.mattermost.rn` for all log entries containing the string `com.mattermost.rn`. I don’t see anything which looks like an error though?

I think you’re on the right track. It’s possible that grepping for only mettermost might be hiding the actual error. I see the line

`ConnectivityManager: StackLog: [android.net.ConnectivityManager.unregisterNetworkCallback(ConnectivityManager.java:5076)]`  
and the answer is probably under there. I am not a Java / JavaScript developer (nor any kind of developer!) and get lost pretty quickly. Hopefully someone who’s smarter than I am can help.

You might also try [Mattermost](https://community.mattermost.com/core/channels/native-mobile-apps)

Oh that’s much easier. But whom do I email the log?

If you had a paid subscription, there’d be an easy answer there! Here, I can suggest looking at the logs to try to figure out what’s going on. Or post the relevant section and hope someone who understands mobile apps can tell. I try to do my best, but I’m not a developer.

From looking at it I think the assumption is right that it has to do with IPv6. It tries to connect to an IPv6 address and fails. It never falls back to IPv4. Do I need to complain with Vodafone? But Mattermost is really the only app with the issue, so they would certainly point back.

This looks like it probably is an issue with the Android app. [Android app can't connect if server isn't listening on IPv6 · Issue #24703 · mattermost/mattermost · GitHub](https://github.com/mattermost/mattermost/issues/24703)

I’ll ask around if this is being worked on. FWIW I got zapped by this too… set up a new instance and couldn’t connect from my home wifi. I turned off wifi on my phone and connected over cellular, and haven’t had an issue connecting since.

So, it sounds like we’re dependent upon OkHttp for this. When they fix it, we’ll be able to fix it! [Change Log - OkHttp](https://square.github.io/okhttp/changelogs/changelog/)

The problem has vanished. Not sure when exactly and why. Was there an update? I now have the mattermost app 2.19.2.  
The system was updated to Android 14 a few days ago.

This issue has come back. A regression?

Is there a solution for this? Would changing the router help?

Do you have a link to the actual issue in OkHttp? (Not the change log) which version of okhttp is in the current mattermost android app?
