AWS lightsail container: API calls blocked

Hello abed765, sorry to hear about your challenges with LightSail and Brevo's API.

When using AWS Lightsail containers and experiencing issues with outbound calls to external APIs (such as Brevo's API), there are a few potential reasons for this behavior. Here are some steps you can take to diagnose and resolve the issue:

Check Security Groups: While Lightsail containers don't support the traditional EC2 security groups, they do have a networking configuration that is similar to security groups. Make sure that the networking settings for your Lightsail container are allowing outbound traffic on the necessary ports for Brevo's API. You can check this by going to the Lightsail console, selecting your container service, and then navigating to the networking tab to review the settings.

Review VPC Peering: If your Lightsail container is in a Virtual Private Cloud (VPC), make sure that VPC peering or other network configurations are not blocking outbound traffic to Brevo's API.

Proxy Configuration: If your container needs to route outbound traffic through a proxy server, ensure that the proxy settings are correctly configured within your container environment. This is especially important if your Lightsail container is in a private subnet without direct internet access.

Check for DNS Issues: Ensure that your container's DNS settings are configured correctly. If the DNS resolution is not working, your container may not be able to reach Brevo's servers even though it's sending out requests.Here are some tips that hopefully resolve the issue for you:

Hopefully this helps resolve the issue.

Thank you and good luck!

My bad. The issue was with how I was reading the API response status code sent back from the server.
