/dev/pts/0 being in use will make no difference.
You put this in root's crontab, so tmux will be running as root, is that
what you intend?
If so and you still cannot attach as root, then likely your script is
failing for some other reason so you will need to debug it.
Does the script work if you run it manually?
What if you run it from cron like this:
/bin/bash -x /path/to/script 2>/tmp/log
Does /tmp/log show errors? You may want to add "|| exit 1" to all the
commands to work out which one it stops at.
