I have two lambda functions. One connects to an ECS instance using a VPC. The second should also connect to that same ECS instance and an API (api.twitter.com). The first function works perfectly, i've been able to write and read from files within the instance. However, the second can connect to the API without the VPC, but immediately the VPC is added it gives me a ``` "errorMessage": "Failed to send request: HTTPSConnectionPool(host='api.twitter.com', port=443) ``` **About my VPC** - I have 2 public subnets and 2 private subnets - in two separate availability zones - I have an Internet gateway attached to my VPC - I have 2 route tables(public and private - My internet gateway is routed to my public route table - I also have an NAT gateway connected to my public subnet - That NAT gateway is routed to my private route table I have gone back and forth with all the connections highlighted above trying to solve this issue. I need my function to access ECS and also connect to the internet API. Please help me.

I am facing the exact same issue, the lambda with vpc connected cannot request to external network (verify google recaptcha). I basically have the same VPC configuration with you. Did you find any solutions?

VPC security group outbound rule is at default set to all traffic, and destination anywhere 0.0.0.0/0 Inbound rule is also at default with all traffic source from security group id

Can you use the VPC Reachability Analyzer to see where the blockage is between the Lambda ENI and Internet Gateway? https://docs.aws.amazon.com/vpc/latest/reachability/what-is-reachability-analyzer.html

Does this help? https://aws.amazon.com/premiumsupport/knowledge-center/internet-access-lambda-function/
