How to configure aws cli v2 for accessing ECS buckets

Hello,

We have ECS servers managed by another team. How can we use aws cli v2 to access the ECS server with key and secret? It is working for C# code to access the server. But aws cli always returns "An HTTP Client raised an unhandled exception: 'NoneType' object has no attribute 'rstrip' ".

Run the cli with --no-verify-ssl and --debug shows exception from urllib3\connection.py.
