In my case (In Debian 9 by Gnome 3.2) selecting the password option "Store the password for all users" in the VPN settings got it working. All other options produce the mentioned error.

Not a solution, but a workaround. You can connect using the command line and also enter the username/password on the command line, therefore the secret agent is not needed.
<pre><code>nmcli connection
nmcli --ask connection up &lt;vpn&gt;
</code></pre>
You first list the connections and then place the ID of the vpn listed into as to the second command. It will then try to connect and ask for your credentials.

This error can also happen if the VPN key file is not readable.
In my case, I have the VPN keys in a Truecrypt volume. That volume was wrongly remounted by root, and only readable by root.
After remounting it as my user, thus giving me access to the VPN keys again, the error went away.
Selecting &quot;Store the password for all users&quot; in the VPN settings as suggested by the other answer also worked, but that was not what I wanted.
So, one troubleshooting step is to check that the needed certificates and keys are accessible.

In my case, I had to have a look at the syslog to get useful information, and I found the following:

I surmise that I had xl2tp running as a service, and strongswan couldn't do its thing because trying again after the following resolved my problem:

I ran into this issue on PopOS 20.04 and 22.04 when using i3 and openconnect. The solution was to add the following to my i3 config:
<pre><code>exec --no-startup-id nm-applet
</code></pre>
After adding this (and restarting i3), I can connect to my VPN using either <code>nmcli</code> in a terminal or the <code>gnome-control-center</code> GUI. Also, nm-applet adds an icon into the i3status bar displaying WiFI signal strength and VPN connection status.

I am using Arch Linux with Gnome and I want to use <code>openconnect</code> to connect to an VPN server. I can do this at the command-line without a problem, but I can't do this with Gnome; I get the following error:

<pre><code>NetworkManager[589]: &lt;error&gt; [1475998103.4381] vpn-connection[0x28a9530,dc5d3708-967d-4e50-90ac-d0c892fe8ab3,"nm-vpn-connection.c",0]: Failed to request VPN secrets #3: No agents were available for this request.
</code></pre>

The <a href="https://wiki.archlinux.org/index.php/NetworkManager#VPN_not_working_in_GNOME" rel="noreferrer">ArchLinux Wiki</a> suggests to do: 

<code>ln -s /usr/lib/networkmanager/nm-openconnect-auth-dialog /usr/lib/gnome-shell/</code> 

but this also does not solve the problem.

The problem occurs when I click on connect; I am unable to activate the VPN connection with Gnome and NetworkManager.
