NEED HELP Way Point Won't Connect

So, although not happening now (somehow, and maybe it’s been fixed but this is just in case it hasn’t) Halo Way Point has usually been showing up on my laptop as having unexpectedly closed the connection. Only happens on my laptop, and for some reason only on my wi-fi (went over to someone else’s house the other day, connected to their internet, and it worked fine but the same day I came back home and it once again didn’t work). In case this happens again, does anyone have a solution? Has this happened to anyone else? Tried some strategies shown on the internet but none worked.
