Are you using NetBird Cloud?

I've tried this on both selfhosted and managed.

Android version 0.0.23

NetBird status -d output:

Additional context

I don't have this issue on my iPhone connected to the same Netbird network.

I'm using a Pixel 7 Pro running Android 14.

Hi @JonathanHohimer,

I don't see a clear indicator of why this happens. The permission-denied errors or the signal disconnects might be. We released a new version that should handle the interface handling better. Could you download and test this version and send new logs if the issue persists? Thanks.

I'm having some similar issue at least since a couple of weeks. The "download speed" ist extremly slow. Like 100kbit/s while upload is as expected. It's leading to an extremely slow connection or even timeouts. Tested in multiple networks (wifi an mobile data). No problems with "plain wireguard".

I got an Pixel 6a with Android 14. On another Android Tablet (Lenovo) no Problems. Maybe some Google Pixel specific issue?

Netbird

"Plain wireguard"

Edit: issue still occurs in 0.28

This is from the debug apk on 0.28.

I'm using a pixel 6 and have noticed similarly slow behavior netbird-1718987482120.log.txt

Also similar behaviour here on a pixel 6 with android 14: unusable slow connection to other netbird peers since a while.

Strangely enough, I also have a pixel 5a on android 14 and this doesn't happen. Maybe only affects pixels after the 5?

I am also experiencing this problem. I have a Samsung Galaxy S22 with Andriod 14. The download speed is very slow when I am using NetBird

I also have a Galaxy S10 with Android 12, and with that phone everything works as it should. The speed is normal.

So for me, if I'm using a phone with Android 14, the download speed is really slow. If I use a phone with Android 12, the speed is OK

At first it was ok with Android 14. So maybe some of the latest security patches?

[purepani]

This has been happening for me basically since I installed the app a long time ago, so it's possible that code that was originally on pixels has been pushed to general android in the android 14

[JonathanHohimer]

Update: I've wiped my pixel7pro and installed the latest Lineage OS and I still have the same issue. So I'm not sure what it could be. :(

Not sure this helps, but I have a few things to add:

1. It doesn't necessarily happen with every peer.
2. Depending on the connection my phone is on, a connection to a peer may be absolutely fine, or slow as molasses. Meaning: I could be having a fine experience connecting to peer X on WiFi, but then have a very slow connection to X when on mobile data, or vice-versa.
3. As far as I can tell, it doesn't seem to be impacted by whether the peer connection is "relayed" or "P2P" (I checked by doing netbird status -d --filter-by-names android-peer-name on the host I'm connecting to). At first I thought it might, because the first time this happened to me was when I was on mobile data, so I thought it could have something to do with my TURN servers.

I also see this issue. No problems at all on iOS, Linux or Windows devices as far as i can tell, but on Android traffic is unbearably slow and basically unusable.
