I need my API to be whitelisted in a client's server so my Firebase Functions must have a public static IP address. So I created a Google VPC connector/Gateway/Cloud NAT to associate a static IP address to my Firebase Function. Everything has been configured properly but I am unable to connect to my function through the given public IP address.
I'm trying to reach it through https://PUBLIC_STATIC_IP_ADDRESS/cloudFunction (for example https://123.123.123.123/v1) but it just does not work. It hangs. I know the IP address is correct because I get a response by pinging it.
Which is the proper way to reach a cloud function through its public IP after associating it to a connector?
