Hi, I'm getting this problem:
1. Run `tmux` in one console window
2. Open up another console window and run `tmux ls` or `tmux attach` etc
3. `tmux ls` etc all report: "no server running on /tmp/tmux-48659/default"
4. But I can see that tmux is still running (connected and working) in the other console
I tried using the -S argument to force the socket location in both the original `tmux` command and the subsequent `tmux ls` or `tmux attach` commands but it didn't help. I can see that the socket file does exist but it still says "no server running".
I'm connected over SSH in case that's important
