I'm getting repeated
NetworkPlugin cni failed to set up pod \"POD_NAME\" network: unable to allocate IP address: Post http://127.0.0.1:6784/ip/LONG_HEX_ID: dial tcp 127.0.0.1:6784: connect: connection refused"
errors in the kubelet log.
Lot's of questions on the internet with this error message, but I haven't found one where anyone actually says what is supposed to be accepting connections on that port. Which is frustrating because if I had that basic piece of info maybe I could figure out what to start/restart to get things working.
