Cloud function URL doesn't work after deployment

Question

Note, this works perfectly when testing locally with Functions Framework.

I just deployed a function

Deploying function...
gcloud functions deploy quantumjs-api --runtime nodejs10 --trigger-http --project qunatumvue --region europe-west2
Deploying function (may take a while - up to 2 minutes)...done.
availableMemoryMb: 256
entryPoint: quantumjs-api
environmentVariables:
  location: production
httpsTrigger:
  url: https://europe-west2-qunatumvue.cloudfunctions.net/quantumjs-api

Edit ---- thanks Doug Stevenson for the ping pointer

However, when posting data to it, I get no response back, just this error:

 "Error: Network Error
    at createError (webpack-internal:///./node_modules/axios/lib/core/createError.js:16:15)
    at XMLHttpRequest.handleError (webpack-internal:///./node_modules/axios/lib/adapters/xhr.js:87:14)"
