Hi everyone, it has been a couple of months that I have deployed a few instances of netmaker starting from 0.9 to 0.11. Initially, ssh and ping would work between nodes. Recently, I am not able to ssh or ping nodes. I also need the DNS but it did not work within the netmaker network. I want to deploy a PWA to one of the nodes, connect an Android device as an external client and install the PWA app.
