I used to have 2 node cluster. I setup a 3rd node using a qDevice (Just a VM running on one of my servers) to be a tiebreaker.
But now I have a 3rd node to add. However, adding it has not been easy. First, I went to remove the qDevice with

FWIW, the two nodes that are currently working and part of the cluster use lets encrypt SSL certificates for the webGUI so I don't get an error. When I added the new host, I didn't set up lets encrypt on it as I didn't think it would be necessary - it was jsut running the SSL certificate it came with.
Edit: This is fixed. I forgot I'd added a new isolated network for the hosts to communicate to each other with.
