Warcraft version problem. You must use Warcraft version 1.24 or above to play. If your version of Warcraft is lower than 1.24. You can play in Fang Hao. Choose to enter the room with version 1.24, and Fang Hao will automatically temporarily convert your version of Warcraft to 1.24.

When you quit the game, the version will automatically revert to the original version.

If you need a patch, you can contact me or play with me. I'm from Education Network.
