Icx-proxy error

Hi all, I want to deploy the local canister and call the function from the canister which is deployed on the IC. So I run “icx-proxy --dns-alias<canister_id>” in one terminal, and run “dfx deploy” in another terminal, then errors comes outs:
“dns error”,
Custom {
kind: Uncategorized,
error: “failed to lookup address information: nodename nor servname provided, or not known”,
Now I know the parameter “–dns-alias” is important, so anyone knows how to config?
