[Bug]: Outline Client can't establish stable connection on Ubuntu 24.04 #2001

Outline Client

Describe the bug

Can't establish stable connection to Outline server after upgrading to Ubuntu 24.04 with my own surely working OK Outline Server, instead client constantly tries to reconnect.

Everything was fine until the upgrade to Ubuntu 24.04, using Outline CLI gets you connected, but the client won't.

I'm including debug log below.

Steps to reproduce

Get Linux machine/VM with Ubuntu 24.04
Install AppImage from getoutline.com
Try to establish stable connection to a server

What did you expect to happen?

No response

What actually happened?

heilkit · 2024-04-28T08:31:00Z

Previously I had Ubuntu 22.04, Outline Client was working perfectly there.

SadeghSalman · 2024-04-29T15:15:09Z

Try

ufw disable

reboot server

and check again.

heilkit · 2024-04-29T17:39:49Z

I have no firewall on my server, my Outline app on the phone works just fine. A windows laptop, that I could get my hands on connects just fine too.

Server:

$ sudo ufw status
Status: inactive

Outline CLI works stable on my Ubuntu machine still.

iloginov · 2024-05-24T13:16:10Z

I am issuing this problem too. I'm using version 1.13.1.

Also, I have to start client with command ./Outline-Client.AppImage --no-sandbox to prevent error "The SUID sandbox helper binary was found, but is not configured correctly".

iloginov · 2024-05-24T19:33:42Z

Also I noticed the following behavior:

Outline-Client runs 2 instances of tun2socks (I see it in ps ax | grep tun2socks)
First instance works permanently but second one (with argument -checkConnectivity) periodically restarts (I see that PID changes in the output of ps ax command)
When I run second one tun2socks from console (I copied it to home directory and start with arguments I saw in ps ax) it reports error Failed to open TUN device: ioctl: operation not permitted. When I run it with sudo it works and does not restart.

I used strace to see that it tries to open /dev/net/tun:

openat(AT_FDCWD, "/dev/net/tun", O_RDWR|O_NONBLOCK) = 3
ioctl(3, TUNSETIFF, 0xc000072bf8)       = -1 EPERM (Operation not permitted)

Also, on fresh Ubuntu 24.04 Outline-Client reports error

FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_OutlinMA3Lfs/chrome-sandbox is owned by root and has mode 4755.

when I start it without --no-sandbox.

It seems like SUID sandbox is the key here.

For now I use outline-cli from outline-sdk package.

AdriCQ · 2024-06-01T10:13:46Z

I have the same issue. How can i solve it ?

jyyi1 · 2024-06-03T19:51:44Z

Hi @heilkit @iloginov @AdriCQ , the sandbox issue seems to be caused by a known electron bug: electron/electron#41066.

You may try these arguments when launching Outline: --no-sandbox --disable-gpu-sandbox.

And yes, please also feel free to continue using outline-cli instead.

li11amy · 2024-06-12T20:31:01Z

the same problem :(

pffont · 2024-07-09T17:09:00Z

Same problem here with ubuntu 23.10

I noticed these messages in the NetworkManager logs when the client is in the connect/disconnect loop

jyyi1 · 2024-07-09T22:09:37Z

Thanks @pffont for the logs. Outline will disable IPv6 when connecting:

outline-apps/client/electron/linux_proxy_controller/outline_proxy_controller.cpp

Line 402 in 13931fa

toggleIPv6(false);

It's weird to see IPv6 routing logs, I'm not sure why. Maybe you can try the outline-cli mentioned above to see whether the same issue happens?

same problem after updating to ubuntu 24.04

VijitCoder · 2024-09-02T17:23:47Z

For an error such as

You need to make sure that ... chrome-sandbox is owned by root and has mode 4755

Using --no-sandbox is not recommended for security reasons.

So you can unpack AppImage archive and set owner/mod for the file chrome-sandbox like it said above. And then run Outline via AppRun.

Here is the commands. Suppose you downloaded Outline-Client.AppImage to ~/downloads:

cd ~/downloads
chmod 0766 Outline-Client.AppImage
./Outline-Client.AppImage --appimage-extract
cd squashfs-root/
sudo chown root:root chrome-sandbox 
sudo chmod 4755 chrome-sandbox

You'll got this:

Now run ./AppRun, connect and see what you got:

$ ./AppRun

not sure the same but with ubuntu 24.04 i have "Unable to Connect: Invalid Access Key Error" (Jigsaw-Code/outline-server#1591)

goroption · 2024-09-07T11:57:50Z

found a temporarily solution from another discuss - turn off ipv6 on active interface
Right now problem is solved for my ubuntu 24.04

ibobak · 2024-09-18T21:12:06Z

I have exactly the same issue after upgrading to Ubuntu 24.04

I applied this patch

cd ~/downloads
chmod 0766 Outline-Client.AppImage
./Outline-Client.AppImage --appimage-extract
cd squashfs-root/
sudo chown root:root chrome-sandbox 
sudo chmod 4755 chrome-sandbox

as it is said above, and now it is running.

However, as soon as any traffic is happening, I am getting these messages in console:

using tun2socks to check connectivity
[EXIT - tun2socks]: Exited with code 0
reconnecting to 78dbda82-2259-4670-826c-7a3f83c2b6e0

...

and they are repeating and repeating: I am getting messages every second that something is being reconnected. What might be the problem?

ibobak · 2024-09-19T07:09:46Z

Dear developers of Outline, you did really a great job, but with Ubuntu 24 something is terribly wrong: connection is always lost, reconnecting multiple times. This needs to be fixed. It doesn't have to be like that.
