I'm having a little trouble getting my client to connect. I'm able to have ngrok tell me the port, but when I go to the client and execute:
ssh pairup@ngrok.com -p 57613
I get
ssh_exchange_identification: Connection closed by remote host
Any ideas why this is happening? I'm on a Mac, and I followed these steps: https://www.adaptivelab.com/blog/pair-programming-with-tmux/
Thanks a lot for your time
