i got problems to enter in online mode PC

so i bought FH4 today on PC and i cant join online. it shows me error and unable to play forza online.
so my xbox live network is ok, there is no any errors.error


I get this all the time, the fix for me is the following:

Go to your windows search bar and type " services " > press enter, a window will pop out, on the right side scroll until you find IP Helper ( just click on something and pres " i "
until you find it ) , right click on it > properties and press Start, also make sure " Startup Type " is on Automatic, mine is but is still going off, so whenever online is not working I just start it, usually right before I start the game. Hope works for you too.
