Get connection errors when trying to use

Did the kubectl create -f kubernetes-manifests/dev/, which brought everything up, but when i try to access the frontend Pod via the NodePort, all I get is an "Uh-oh!" and the following error: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp 10.152.183.174:3550: i/o timeout" could not retrieve products main.(*frontendServer).homeHandler /src/handlers.go:59 net/http.HandlerFunc.ServeHTTP /usr/local/go/src/net/http/server.go:2042 github.com/gorilla/mux.(*Router).ServeHTTP /go/pkg/mod/github.com/gorilla/[email protected]/mux.go:212 main.(*logHandler).ServeHTTP /src/middleware.go:81 main.ensureSessionID.func1 /src/middleware.go:103 net/http.HandlerFunc.ServeHTTP /usr/local/go/src/net/http/server.go:2042 go.opencensus.io/plugin/ochttp.(*Handler).ServeHTTP /go/pkg/mod/[email protected]/plugin/ochttp/server.go:86 net/http.serverHandler.ServeHTTP /usr/local/go/src/net/http/server.go:2843 net/http.(*conn).serve /usr/local/go/src/net/http/server.go:1925 runtime.goexit /usr/local/go/src/runtime/asm_amd64.s:1374

This is running on a MicroK8s cluster, using Calico as the CNI.
