There are two boxes on the left of DNF official website landing box, called NEXON, and on the right called DF and Right. The left and right ports are different and cannot be mixed. For example, the port on the left is not allowed to log in to the port on the right. The slogan on the left is NEXON's account, and the slogan on the right is that the original DF was operated by hangame and later transferred to NEXON. I didn't get Sawaguchi because I only had hangame account. That is, DF number. Later, after NEXON's operation, left and right ports appeared. When buying a DF account, you must find the right port. Cannot log in DF number. You can't log in to the port on the left. The left port is for karting, Loki and other games. The DF number is independent.
