Can't update Agent - Battle.net on Fedora 28

Pretty much a fresh install, can’t get the current battle.net installation working.

I’m getting the following error: 0042:err:wininet:open_http_connection create_netconn failed, followed by the battle.net agent crashing.

I have all the prereqs installed from the github page.

Edit with a bit more info:

Here are the packages I have installed, should cover all the prereqs:
