There are some problems with the warlord

[zzzz100062 0]

Firstly, after I finished making the warlord's level in the eden, when I want to play in multiplayer mode, I found that when I entered the multiplayer game, clicking the respawn button, however I got stuck on the respawn page, did'nt enter the warlord game. (like the picture )

I am not sure if I adjust or misadjusted something a part of it, I hope someone who knows how to solve it.
