TLS certificate error

[kqian-godaddy]

Hi,

I used this lib to connect to AWS RDS proxy. But i got error like:
x509: certificate signed by unknown authority

I'm doubting it's due to https://github.com/shogo82148/rdsmysql/blob/main/v2/certificate_gen.go. Do you have any idea?

I forgot to test AWS RDS Proxy...
RDS IAM authentication uses its own Root CA (https://github.com/shogo82148/rdsmysql/blob/67b44f184a5602e8a810a36ae5e177a24cefbfea/v2/certificate_gen.go), while AWS RDS Proxy uses certificates signed by ACM.

https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/rds-proxy.howitworks.html#rds-proxy-security

RDS Proxy uses certificates from the AWS Certificate Manager (ACM). If you are using RDS Proxy, you don't need to download Amazon RDS certificates or update applications that use RDS Proxy connections.
