We are having issues connecting to the API from an Azure VM. As a test I’ve tried typing https://api.companieshouse.gov.uk into a web browser running on an Azure VM you got a connection timed out error message rather than the {“error”:“Invalid authorization header”,“type”:“ch:service”} json response that my local browser gives.
Is the a connection/firewall issue between your amazon hosting and Azure? It’s happening on 2 different Azure subscriptions with completely different network setups.
