Horizon 4 only works with internet connection?

My internet went out and I tried to load up Horizon 4 and it comes up with an error that reads “Please try again, For some reason Forza Horizon 4 took too long to start”. I tried loading up Forza Motorsport 7 and it boots right up no problem. Has anyone ran into this problem?

Hi,

Yes, I had the same problem this afternoon. but with me as long as I was at forza in the game was suddenly no longer connected internet, but was at steam online and could write with a friend when I left forza my internet was back, although I was the whole time on the internet , before we went again …

For me its saying “You neet an internet connection to play.” [PC]

It wasnt like that earlier. I guess they did that to sort out the use of some glitch.
