Can this be a SailJail problem?
When I start 9Gag from the app launcher, an error message appears saying “api.9gag.com not found”. If I start it from the terminal, it works. It’s the same with the sfos-forum-viewer. It doesn’t work from the app launcher, but it does work from the terminal.
If I disable SailJail for the app (Sandboxing=Disabled) then it starts too.
