Third party apis not accessible through beanstalk application.

Question

I have a nodejs rest application hosted on elastic beanstalk with load balancer enabled. The application makes external apis calls but not of them are working. One example call is https://www.googleapis.com/oauth2/v3/userinfo?access_token=${accessToken} . I have enabled all inbound/outbound rules to allow traffic from 0/0.0.0.0 on the load balancer security groups, vpc, subnets, but it still doesn't work. I have an internet gateway also attached to the vpc. The subnet has route table with internet gateway.

Answer

Hello.

Does EC2 have a public IP address?  
If a public IP address is not assigned, you will not be able to communicate with the public API even if you launch EC2 in a subnet that has a route to the Internet gateway.  
If EC2 does not have a public IP address, why not try using NAT Gateway?
