Hi guys,
total n00b here. I have a snap that starts a JSON RPC server on localhost. Then I have a snap (lets call it client) that communicates with it. The confinement for both is set to strict. When I install the client with --devmode it works fine. Without it however the client can not find the host. Both are plugged to the network and network-bind interface. Now the question is what Interface am I missing? I read through the list but none seemed the one I am looking for. I worked through all the tutorials and there was one blog about writing interfaces, but I didn’t understood that at all… (how would I change the snap repository and still try it on Ubuntu Core? kind of not understanding the proper work flow here)
So, hope I could articulate my problem clearly 
(not native English speaking)
Thanks
