Permission denied when running tmux in fedora

Hi, I'm new to Fedora and I am trying to run TMUX. I have a fresh install of fedora and I just set up a new user with sudo and installed tmux, however when I try to run tmux I get an error that says "create session failed: permission denied".

I get this same problem when I try to run screen or any other program (ie irssi or weechat)
