3 Huawei AI Cube and street fighter V won't log in

Recently got wireless broadband with 3 and now Street fighter won’t log in. I have tried forwarding ports and changing dns to a alternative which did work for a day but then went back to error. It ps4 and doesn’t have any other problems with any other games just this one. Tried disabling firewall in the router still same problem. Anyone have any ideas what it could be?
