How are you trying to access? What error message are you getting? Are you using "requests" module or something similar as the below code? 

import requests

resp = requests.get("https://api.example.com/data")
print(resp.json())

I'd say I already used that with a trial version without getting issues but not completely sure if I ran that in a serverless cluster...

I changed the set up and I linked it to aws workspace. It doesn't raise any error now.

But I was using requests
