Can't connect to steam

After the update, the online mode has stopped working, I can not fight anyone online. Correct this problem. The Can not connect to steam error appears.

this may or not help, but make sure you have the latest updates and versions of everything … steam, win10, KI, etc.

I also couldn’t connect to Steam. I finally could play today, ranked was working and I also got my golden rank back (I was playing for the grind, but after the update I was put in qualifiers again, though I didn’t play so the rank fixed itself).
