Nascar heat5 says authentication failed are the servers down ?

You'd want to check with Motorsport Games.

The company no longer has the NASCAR license and all the servers have been shut down

Which servers are we talking about because there aren't any issues announced in the official website Xbox Status | Xbox Support? Also what device are you using?

i am on java edition (pc) and this did not help, it said something similar, "You are not logged into your Minecraft account." and sometimes it says, "Missing profile public key." i have tried to open every single one of my servers about 10 times, and it always says on of those. what does minecraft want from me???

Edit- and now its also saying, "Error: Authentication to Minecraft.net Failed."

Edit2- and now its also saying, "Failed to Verify Username!"

Edit3- im trying to join one of my servers, i thought it was working, but now i need a license??? god im so confused-

Edit4- i know this is the FOURTH time ive edited this post, but, "Failed to authenticate your location!" mah god-

posting for anyone that finds this in the future! the issue turned out to be my IP address. I use starlink (satellite internet) so I used a VPN and it all started working again!
