Access key is not found

Hello all,


Following this documentation https://www.alibabacloud.com/help/doc-detail/55479.htm where it is described how to deploy .war file to EDAS.
Using the same demo.zip, whenever I try to run python build/build.py, I am getting response "Deploy app failed. Ret: 200, Resp {"code":401,"msg":"Access key is not found."} "


Does anyone have any idea what could cause it? I am sure I have put right accesskeyID and secret in build/.osscredentials config file.
Also I am using RAM user where I generated my own AccessKey not with the primary account.


I would be really thankful for any help.


Also when trying to follow this guide - https://www.alibabacloud.com/help/doc-detail/62123.htm I am not able to connect to any of the endpoints as when running the code it always gives me -
"Exception in thread "main" com.aliyuncs.exceptions.ClientException: SDK.ServerUnreachable : Server unreachable: java.net.UnknownHostException: edas.ap-southeast-1.aliyuncs.com

Caused by: java.net.UnknownHostException: edas.ap-southeast-1.aliyuncs.com  "

Also using aliyun CLI there is no luck -  trying to run
$ aliyun ecs DescribeRegions
this is what I am getting -

ERROR: [SDK.TimeoutError] The request timed out 4 times(4 for retry), perhaps we should have the threshold raised a little?

I am located in Europe.

Thank you!
