Connection Refused over port 22

[Ethan Kavanagh]

Hi,

Currently have a raspberry pi 3b+, with a cluster hat v2.2 with 4 zero w's on it. However i cannot ssh between the 3b+ or any of the nodes. Am i doing something wrong? I have tried ifconfig -a and it seems to be picking up all of the nodes. I have noticed that my IP's all have 180, where as teh instructions all have 181. The ssh server is working fine, i can ping outside websites and can also ssh into the node itself.

edit - i am doing this all over wifi, i seee that the .181 address is assigned to br0, does this need to be wlan0 for it to work?
