.net core batch job and pool delete operations fail to authenticate

Having some issues with the the pool and job delete operations when running .net core 1.1, version 6.1.0 of the SDK.

ClientRequestId:
RequestId xxxx
HttpStatusCode:Forbidden
StatusMessage:Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

Error Code = AuthenticationFailed, Lang=en-US, Message = Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.
RequestId:xxxx
Time:2017-05-05T07:51:18.6188868Z
Additional Values:
Error Details key=AuthenticationErrorDetail value=The MAC signature found in the HTTP request 'xxxx' is not the same as any computed signature. Server used following string to sign: 'DELETE

Getting this error on:

• BatchClient.PoolOperations.DeletePoolAsync
• batchClient.JobOperations.DeleteJobAsync
• BatchClient.PoolOperations.DeletePool
• BatchClient.JobOperations.DeleteJob

All the other operations are working, but these two won’t authenticate.

Read that this might be a issue with a proxy cache, any way to disable that when running the sdk? https://social.msdn.microsoft.com/Forums/SqlServer/en-US/67183d62-60ab-4ef0-a1ca-b765d85ea2f6/authenticationfailed?forum=azurebatch

Any quick solutions?
