Same for me on Ubuntu 18.04 for protonvpn-cli 3.11.0-7

It happens to me too, with ProtonVPN CLI v3.11.1 (protonvpn-nm-lib v3.8.0; proton-client v0.7.1).
OS infos:

OS: Arch Linux x86_64
Kernel: 5.16.15-arch1-1

UPD: I had the networkmanager-strongswan package installed.
There was such an error in the logs:

After deleting the networkmanager-strongswan, it was possible to connect. But this is not a solution, because I need these package

I fixed it by doing the following.
If you type protonvpn-cli —get-logs the folder containing the logs will be opened.
protonvpn-cli.log is the one containing the error (in my case)
The log ended with the following traceback:
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.NetworkManager was not provided by any .service files
so i started network manager and i could connect.
sudo systemctl start NetworkManager
But while i was connected with a dutch server, my internet was not working.
So i enabled network manager and rebooted.
sudo systemctl enable NetworkManager
After reboot all worked as it should.

I hope this helps you guys too.

Maybe you can resolve this issue by creating a symlink in «/usr/lib/NetworkManager/libnm-vpn-plugin-strongswan.so»

Just installed on Ubuntu server 22.04 LTS (jammy) using Proton VPN CLI v3.12.0 (protonvpn-nm-lib v3.10.0; proton-client v0.7.1) and connecting via UDP connection.
I have tried using renderer in Netplan as NetworkManager, but this made no difference.

Same issue persists for several months. (Proton VPN CLI v3.12.0 (protonvpn-nm-lib v3.11.0; proton-client v0.7.1))

Linux demetrio 5.4.0-109-generic #123-Ubuntu SMP Fri Apr 8 09:10:54 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

Message from newest client (just upgraded) is:

$protonvpn-cli c -f

Setting up Proton VPN.
Connecting to Proton VPN on JP-FREE#3 with UDP.

Unable to connect to Proton VPN: Proton VPN connection has been disconnected. Reason: VPNConnectionReasonEnum.UNKNOWN_ERROR

Earlier client version just printed:

An unknown error has occured. Please ensure that you have internet connectivity.
If the issue persists, please contact support.

Legacy cli client:

$protonvpn -v
ProtonVPN-CLI v2.2.4

Prints next output:

$sudo protonvpn c -f

There is already a VPN connection running.
Terminating previous connection...
Connecting to US-FREE#49 via UDP...
[!] There was an error with accessing the ProtonVPN API.
[!] Please make sure your connection is working properly!
[!] HTTP Error Code: 422

But looks like it is actually connects, because I was able to get access to blocked resources, while newest versions is not working at all.

P/S: Servers from VPN Plus (Basic previously) plan also doesn’t work.
P/P/S: I’m really thinking about stop my subscription and switch to another VPN service provider, please fix this issue.
P/P/P/S: Android client connected to the same WiFi works well, but I have two laptops with ubuntu and both doesn’t work, so I believe issue relates exactly to a client, not network.

I know there is protonvpn-cli --get-logs command, but it generates a folder (30mb) with a lot of files, and I’m paranoid about sending it because probably some of them may contain sensitive data.
I don’t know but maybe you can add -v attribute that prints all steps while connecting for such situations and output all things that may go wrong?

I had this problem recently, and deleting ~/.cache/protonvpn fixed this. May need to run protonvpn-cli d once before/after doing it.

Deleting ~/.cache/protonvpn doesn’t help.

But I found a logs in this folder:

IIRC, I also had a similiar issue [1]. ProtonVPN logs it couldn’t connect to ProtonVPN server when it works fine in other devices connected to same network, and it started working when I deleted the cache folder. So there’s something really wrong with the library related to connectivity.

Edit: What I mean is that I also saw that in the log (iirc).

Same problem in ChromeOS. Just installed and tried to run it, after logging into it.

Doing ^ and re-running the CLI / restarting my GUI worked for me.

Setting up Proton VPN.
An unknown error has occured. Please ensure that you have internet connectivity.
If the issue persists, please contact support.

same..

I had this problem recently, and deleting ~/.cache/protonvpn fixed this. May need to run protonvpn-cli d once before/after doing it.

This works for me. I deleted and ran protonvpn-cli after and it connects now.

has anyone got this working?

Some few days ago I had this issue again, but in arch linux then. Solved by running nm-applet before trying to connect to it.

I have this same issue on fedora 36. Oddly it works fine from a terminal window within gnome on the box… but if I ssh in to that same box and try the same protonvpn-cli command it fails with this message…

An unknown error has occured. Please ensure that you have internet connectivity.
If the issue persists, please contact support.

The main reason I want to be able to use the cli is so I can ssh into a box and connect it to a vpn so why it doesn’t work while sshed in but does work while in a terminal on a box is beyond me.

Ok so if I follow the journal and issue the protonvpn-cli command I get this if I am sshed in…

Nov 14 11:09:15 sys76 NetworkManager[8183]: <info>  [1668442155.1003] audit: op="connection-add" pid=248358 uid=1010 result="fail" reason="Insufficient privileges"

If I preface the command with sudo I get a warning that running it as root is not supported and is highly discouraged.

What would make the permissions of my terminal user within gnome differ from my permissions as that same use while ssh-ed in?

Found a solution to my problem above… (at least on Fedora 35)

create this file as root, change USER for your user name….

cat /var/lib/polkit-1/localauthority/50-local.d/10-network-manager.pkla
[allow USER to modify all network states and settings]
Identity=unix-user:USER
Action=org.freedesktop.NetworkManager.*

ResultActive=yes

systemctl restart NetworkManager

Happy I tested the cli-tool before upgrading my plan to ProtonVPN Plus..

Unfortunately for me, I’m still paying for ProtonVPN Plus… probably it is time to migrate to mulvadvpn or smth else…

I’m just going to leave this here because I did find the answer. ProtonCLI does not support Ubuntu Server. It requires an os with a display.

I was able to login on ubuntu server, but only directly from the console’s terminal and not through ssh. You could try that

I had this problem recently, and deleting ~/.cache/protonvpn fixed this. May need to run protonvpn-cli d once before/after doing it.

worked for me also, on Ubuntu Mate 20.04 (running in a VM)

I’m running PopOS 22.04, based of Ubuntu LTS, protonvpn-cli is giving my this error right now due to not being able to resolve protonstatus.com. Cross-checked with online tools, and it seems down.

Protonvpn-cli uses NetworkManager to configure its connection but Ubuntu 22.04 uses systemd-networkd instead, therefore the whole issue.

An option would be to setup ubuntu 22.04 to use systemd-network instead but you will face new issues non-related to protonvpn I believe…

Came here to say that I’ve had no problems with ProtonVPN cli on Fedora, but am having this same issue with Ubuntu Server as everyone else.

From SSH, I get the above error («An unknown error…»)

From console, it actually tries to connect, but just stays there. My screen reads:

Connecting to Proton VPN on CH-AR#10 with UDP

I thought it was stuck on that for the past few minutes, but I couldn’t even Ctrl-C out of it.

Same for me both with Ubuntu 22.10 and Debian 11 (an unknown error has occurred….), and both using the cli and the gui interface of protonvpn. Has anybody found a fix (besides moving to another linux distribution)?
