PC Flight Program

I can’t connect my steam account to HaloWaypoint as every time I attempt to sign in it says I’ve failed too many times to attempt to sign in, but I’ve waited 4 days now before trying again and it still gives me the same error message (and I’ve even signed out of steam and resigned in to make sure all the information was correct) and I’m lost at what to do next, any advice would be much appreciated.
