Connection Failed - Purchased today
Purchased the game via Steam today and am not able to get past the joining online services page. It always returns this message: Weirdly, I can still connect and play previous Battlefield title...
Just an update if anyone comes across this post. I spoke with my Internet provider and they removed "CGNAT" from my account and then I was able to join the servers.
"CGNAT is a technique used by internet service providers (ISPs) to share a single public IPv4 address among multiple customers. While this conserves the limited supply of IPv4 addresses, it can interfere with peer-to-peer (P2P) connections and certain online services."
