Unable to add cert through HTTP Request

[curtis18]

I am using AWS SES in Spring Boot 2.7 to send email via HTTP Request. As the service requires to run behind proxy with a cert. I tried to add it in the config file at ~/.aws/config as below or export REQUESTS_CA_BUNDLE=/etc/pki/ca-trust/source/anchors/thecert.crt, but it is not successful in Spring Boot. However, I tried to use a Python script to send email with boto3 without any problem. If the proxy does not require additional cert, it works too. May I know how to embed a cert in a right way for AWS SDK JAVA if the proxy require additional cert?

[default]
region=us-east-2
output=json
ca_bundle=/etc/pki/ca-trust/source/anchors/thecert.crt

Servlet.service() for servlet [dispatcherServlet] in context with path [/testms] threw exception [Request processing failed; nested exception is software.amazon.awssdk.core.exception.SdkClientException: Unable to execute HTTP request: Network is unreachable] with root cause

Hi @curtis18

Firstly, I edited your issue description to put the stacktrace under a collapsible section, to make it easier to scroll down the thread.

Regarding the error, I don't think java.net.SocketException: Network is unreachable is related to missing certificates, it means the network could not be reached. This can be caused by misconfigured proxies, so I would double check the proxy configurations. Tools like tcp dumps and Wireshark can help you debug the request path through the proxy.

To answer your certificate question, the Java SDK v2 does not support the ca_bundle environment variable, mostly because the certificate validation is made at the JDK level, not at the SDK level. You need to consult your JDK documentation to know how to configure custom certificate paths.
