Empty reply frrom node api

Suddenly cant get anything from node api. Node is up and running.

curl grin:`cat ~/.grin/main/.api_secret`@127.0.0.1:3414/v1/blocks/4 -v

  • Trying 127.0.0.1…
  • TCP_NODELAY set
  • Connected to 127.0.0.1 (127.0.0.1) port 3414 (#0)
  • Server auth using Basic with user ‘grin’
    > GET /v1/blocks/4 HTTP/1.1
    > Host: 127.0.0.1:3414
    > Authorization: Basic <-- my secret -->
    > User-Agent: curl/7.63.0
    > Accept: /
    >
  • Empty reply from server
  • Connection #0 to host 127.0.0.1 left intact
    curl: (52) Empty reply from server

any help would be appreciated.

You are using the wrong port - try on 3413

this is embarrassing…
thanks for your help!
