Comment 35 for bug 1732030

Something seems broken on your config, all those basic things should be allowed IMHO (and they are, or I'd hit them as well).

You could iterate on this with [1] which for this would let you also add "connect".
But I doubt that will eventually resolve your issue.
The question is why does it break on you at all while it is working for others in general.

If you iterate adding more and more excuses you might come back with the list that you needed.
But I'm pretty sure connect and socket would have been allowed already if everything would be right.
