Amazon trados plugin

Hello Dears,

I am trying to use amazon trados plugin so I followed the steps described at the below article

https://community.sdl.com/product-groups/translationproductivity/w/customer-experience/3315/amazon-translate-mt-provider

then used the two ways ( Access key / Secret access key && Locally configured AWS profile) but I got the same below error at both times.

So please could you help me.

Best Regards,
