get_network_available returns false even when api.nasa.gov can be reached

[soconn]

Hello, I've been receiving an odd issue as of late where I'm unable to download new wallpaper. Linux ubuntu 5.3.0-26-generic #28-Ubuntu SMP Wed Dec 18 05:37:46 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux Ubuntu 19.10

The extention states that "Media type video not supported" as well as "No picture today (for quite ome time)"

When I perform a journalctl -o cat -f /usr/bin/gnome-shell I receive the following : NASA APOD extension: refresh: network is not available NASA APOD extension: Next check in less than a minute NASA APOD extension: Refresh done.

Cleared out the folder (permissions 775) and restarted the extension. I am using my own personal API key as well as those that were loaded with the extension. Any ideas?

Mhm... "network is not available" is interesting. Do you have access to the internet?

If you do this code should return true:

const Gio = imports.gi.Gio;
let nm = Gio.network_monitor_get_default();
nm.get_network_available();

You can try to paste that in gjs.

[soconn]

gjs> const Gio = imports.gi.Gio;
gjs> let nm = Gio.network_monitor_get_default();
gjs> nm.get_network_available();
false

I do have internet access - I was pulling containers just prior. This is on a development VM on VM-Workstation, unsure if that matters. Is there a specific port gjs uses? Thank you for looking into this by the way!

Apparently get_network_available is too dumb for your case.

"Available" here means that the system has a default route available for at least one of IPv4 or IPv6.

you can try what happens with nm.get_connectivity(); or nm.can_reach(new Gio.NetworkAddress({'hostname': "api.nasa.gov"}), null);, but that's a way more expensive check.

Get connectivity provides a 1, the others err'd out (chances are I'm not inputting them correctly as I'm not knowledgable in gjs

gjs> const Gio = imports.gi.Gio;
gjs> let nm = Gio.network_monitor_get_default();
gjs> nm.can_reach(new);

Yep, you shouldn't paste the line break in the middle of the command, but never mind, that's still not a solution.

However why you don't have a default route? Can you post the output of ip route?

So there is a default route. I'm clueless. Somehow NetworkManager thinks there is no internet connection. get_connectivity() = 1 means local connectivity only.

It's probably an issue with the way I have the VM networking set up. I'll mess around with it and if I discover anything, I'll come back and post the solution. Thanks for looking at this with me.
