Empty reply from server

Can someone help me understand why after i open a valid connection to neo4j

connection <- neo4j_api$new(
  url = "http://localhost:7687", 
  user = "neo4j", 
  password = "password"
)

connection$ping()

200

After calling the classical

'MATCH (n) return n' %>% call_neo4j(connection)

I got the following error?
Error in curl::curl_fetch_memory(url, handle = handle) :

7687 is the bolt port. You should use the http port - usually 7474

Even with port 7474 is not working. And user is neo4j, password is password, because I am using the python driver similarly and there it works in that way.
The problem is not the ping itself that I know it is a bit buggy, but i get an API Error after the query.
