Error validating the SSL configuration: Invalid server certificate

[nbari]

I am trying to install codedeploy-agent on-premises, the VM is using:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.4 LTS
Release:        20.04
Codename:       focal

this is the installation flow starting with ruby:

apt install ruby-full

Get the installer:

wget https://aws-codedeploy-us-east-2.s3.amazonaws.com/latest/install

chmod +x ./install

Install the desired version, latest since writing this:

Latest available:

 ./install auto -v latest/codedeploy-agent_all.deb

or with

 ./install auto -v releases/codedeploy-agent_1.3.2-1902_all.deb

The configuration file /etc/codedeploy-agent/conf/codedeploy.onpremises.yml:

---
aws_access_key_id: ACCESS_KEY
aws_secret_access_key: SECRET_KEY
iam_user_arn: arn:aws:iam::023333984930:user/CodeDeployUser-test
region: us-east-2

But in the logs I get:

Error validating the SSL configuration: Invalid server certificate...

Here the full log:

Any ideas of what could it be wrong?

I had to block requests to the metadata endpoint from the existing provider:

iptables -A OUTPUT -d 169.254.169.254 -j REJECT
