No connection to graphql

//pluginas.js graphql: { enabled: true, config: { playgroundAlways: false, defaultLimit: 10, maxLimit: 20, apolloServer: { tracing: true, }, }, },

endpoint should be:
but i dont get any connection?
ofc on dev localhost it works thru a tunnel provided within the plugin @creazy231/strapi-plugin-apollo-sandbox
but localhost:1337/graphql doesnt work either.
all so confusing.
I use local to create graphql queries and i dont mind if it is thru a tunnel but on the production server i just need a connection to the graphql server with introspection enab led?
