App hangs on connection

[foxfriday]

I suspect protonvpn needs nm-applet and a notification server. When I start np-applet with notifications disabled (nm-applet --no-agent), protonvpn hangs during the connection. For me, enabling notifications (taking out the --no-agent flag and having a server) fixes the problem.

[calexandru2018]

Well the agent is needed mostly for NM because the openvpn password is stored in the keyring. Some versions of nm-applet implement this while others dont (Lubuntu and the nm-tray problem), specifically:

One thing to consider is that nm-tray does not support password asking, so either you save the password FOR ALL USERS or you will need to connect differently.

And this is key here, since the "store password only for this user" won't work on lubuntu systems that use the native nm-tray because NM will need to ask keyring for the password, thus users wanting to use our app will need to switch to nm-applet.

As an example, I'm running Manjaro with Gnome (5.10.42-1-MANJARO) and I don't have the network-manager-applet package installed. Currently, nm related packages installed on my system are:

• nm-connection-editor <- allows to edit VPN configs via GUI
• libnm <- network manager library
• libnma <- network manager GUI library
• networkmanager and it's different vpn plugins
• glib-networking <- network extension for Glib (manage NM via glib)

[joshbowyer]

Bumping, would it be possible to simply check for nm-applet and if its not present to connect without it? That way if its present the functionality isnt removed but if its not then it doesnt fail

[calexandru2018]

Hey @joshbowyer

Does the issue persist after the latest update ?
Also, in regards to the kill switch yes that is correct. When you don't have libindicator installed, when you press on the X the app actually ends, but the permanent Kill Switch remains in its place.

[joshbowyer]

So it looks like it just fails to connect. It creates the three network devices (*intfr0) but after a while the connecting screen eventually just shows a Close button and returns to the main screen which still says not connected, and I have no network connectivity.

[calexandru2018]

Hey @joshbowyer please ensure you're running on the latest versions.

[joshbowyer]

I am. I just updated this morning from the official repo.

[joshbowyer]

Are there logs I can check? Or does it just bootstrap NetworkManager?

[calexandru2018]

Hey @joshbowyer

You can check the logs via the following commands:

• journalctl -eu NetworkManager
• cd ~/.cache/protonvpn/logs && ls -la then you can choose which files you would like to look at

If you don't manage to figure it out, you're more then welcome to reach out to our incredible support team at: https://protonvpn.com/support-form which will help you out.

The following appears to be the issue:

[joshbowyer]

That stuck out to me too, but what is causing that? I have an initialized keychain

[calexandru2018]

By noagents it can be multiple things. Either something is miss-configured or nm-applet is missing, or that the specific plugin of NM is custom made and results in undesirable effects, something very similar to this: https://manual.lubuntu.me/stable/G/AdvancedNetworking.html

[joshbowyer]

nm-applet is indeed missing (as this isn't a shell that uses applets). Can this be changed? Maybe a simple conditional to check which shell is being used or something? And to ignore/continue if it's a shell without applets (phosh for example)?

[calexandru2018]

@joshbowyer it's a dependency for NetworkManager to work properly.

Could you try the following:

• Download .ovpn file from your account: https://account.protonvpn.com/
• Import it into NM via either NM-CLI or NM-GUI
• FIll in the openvpn data
• Select "Store password for this user only"
• Save the VPN connection
• Attempt to connect
• Provide feedback

[joshbowyer]

The connection works either way.

[regazzoj]

Hello,

I have the same issue because I am using nmtui instead of nm-applet to manage my connections.
If I run nm-applet, connection start as expected.
But I would really like to use only nmtui, do you think it is possible to do so ?

Let me know if I need to open a new issue.

Thanks for your help !

[joshbowyer]

I have all the Debian equivalents of those installed but it doesnt work. Did you see the error log I posted here showing an incorrect amount of arguments?

[calexandru2018]

@joshbowyer if you referring to

__dynamic_callback:124 — Exception: NM.Client.add_connection_finish() takes exactly 2 arguments (1 given)

Then it's most probably not the cause. If this was the cause then the results would've been different. Either way this has been fixed, and should ship with next update.

[amanzag]

I'm having a related issue (#9). I use KDE and by default this nm-applet is not running.
Protonvpn fails to connect unless I explicitly start nm-applet.

Has the dependency to nm-applet been removed?

[zerotobtc]

So we have to explicitly run nm-applet in an additional window every time we want to connect? Isn't there a workaround where nm-applet can automaticaly run in the background?...

[joshbowyer]

Bumping again, the app is currently unusable without nm-applet and many distros now dont ship with it

[ediowar]

Is the connection established on the second try?

[joshbowyer]

Nope

[Excal-rs]

similar issue also on manjaro kde. latest protonvpn version
