AWS SSM / Patch Manager Windows / SSL Error

HI,

I tried to use AWS SSM Patch manager for a Windows 2019 instance.
I' used S3 VPC Endpoint with a private route53 hosted Zone.
The SG of the S3 endpoint allow https and http.

In the SSM logs it seams I have a SSL certificate issue but I do not know how to solve this issue.

Preparing to download PatchBaselineOperations PowerShell module from S3.

Downloading PatchBaselineOperations PowerShell module from https://s3-eu-west-3.amazonaws.com/aws-ssm-eu-west-3/patchbaselineoperations/Amazon.PatchBaselineOperations-1.35.zip to C:\ProgramData\Amazon\SSM\InstanceData\i-0e71b155c8a6cbe29\document\orchestration\84e87dc6-d218-45de-bb2a-e3d855cabe3b\PatchWindows\Amazon.PatchBaselineOperations-1.35.zip.

Have you ever encountered this issue ?

Thanks
