I experienced the same issue. After some debugging, the line causing the problem is here.

When I check the file permission on /tmp/vim_multi_player_pipe_*, it is prw-rw----

Since multiplayer.vim using these pipes for communication, so other users cannot open this pipe. I guess the test environment for multiplayer.vim might be different than ours, so it fails as you indicate.

Solution one:
$ umask 20
note: it will make all files you create allowing other users to read and modify.

Solution two:
$ (umask 20 && vim filename)
note: umask will only affect vim file and /tmp/vim_multi_player_pipe* creation. Not sure it will open a security hole for your vim.

Solution three:
Clone the project and change the line as this.

After this change, this very-well-made plugin works in my multi-user system! Still learning how to use it :)
