Can't clone from gitlab.gnome.org

[Exalm]

Cloning git repositories from GNOME gitlab in Builder doesn't work on Ubuntu 17.10.1.

Tried URLs:
https://gitlab.gnome.org/GNOME/gnome-games.git (Failed to resolve address for https: Name or service not known)
http://gitlab.gnome.org/GNOME/gnome-games.git (There is no TLS stream available)
git://gitlab.gnome.org/GNOME/gnome-games.git (Failed to connect to gitlab.gnome.org: No route to host)

Cloning from github works:
git://gitlab.gnome.org/GNOME/gnome-games.git

There's no output in terminal, even with G_MESSAGES_DEBUG=all

Cloning from terminal using "git clone <URL>" works fine for all above URLS.

gnome-builder version: 3.26.1-1ubuntu1

Cloning also works fine in Builder 3.26.3 from Flathub.

I confirmed with Exalm that this is fixed in 19.04. I *think* it's fixed in 18.04 LTS too.

I think this might have been a libgit2-glib issue but I don't remember the details.
