Cannot footloose ssh into created nodes if currently in ssh session

Getting a error when I try to footloose ssh after running a footloose create on network'd nodes ( I followed the 'Using user-defined networks' example)
Output:
$ cat footloose.yaml

$ footloose create

Update: I was working this over an ssh session between two nodes on my local network. It seems to not work in an ssh session but if you run the command locally it does work. Updating title to reflect true issue
Edit: Host is running Ubuntu 20.04, ssh node is running Zorin 15.2 Lite. Attempted on a few different configurations (Fedora 31 local, Fedora 31 ssh'd to Ubuntu 18.04, Ubuntu 20.04 ssh'd to Solas 4 Budgie) and all worked. Seems specific to Zorin
