Can't create Lifecycle Rule, due to error: "Credential should be scoped to a valid region"

Question

I'm trying to create a Lifeycle policy in eu-central-1 for ec2 instances from that region.
I'm selecting an ec2 instance by it's name and I'm giving the policy a name.
My schedule is daily every 24 hours on 3:00 UTC.
I'm retaining 3 snapshots.

I have everything else on default, including the IAM role.

After reviewing the policy and clicking on 'create', I just get the error 'Credential should be scoped to a valid region. '.

When I look in the browser console, the request calls to "https://eu-central-1.console.aws.amazon.com/ec2/alma/iamadmin-proxy?module=storage&call=CreateServiceRol"
and returns a 400 Error "Bad Request" with response body "{"__type":"com.amazon.coral.service#InvalidSignatureException","message":"Credential should be scoped to a valid region. "}"

The error happens both for an EBS Snapshot Policy as well as an EBS-backed AMI policy.
It occurs whether or not I use the root user and whether or not I use a Chromium or Firefox browser.

I therefore am unable to create a Lifecycle rule at this moment.

Answer

Hello.

Is it possible to create it using the AWS CLI instead of from the management console?  
It can be created using the "create-lifecycle-policy" command.

Could you clarify if you are creating this within the EC2 section of AWS Console or somewhere else? https://console.aws.amazon.com/ec2/home#Lifecycle:

The error message is described here https://docs.aws.amazon.com/IAM/latest/UserGuide/signature-v4-troubleshooting.html#signature-v4-troubleshooting-credential-scope

Depending on the method you are using, is it possible to explicitly set the region with something like `--region eu-central-1` ? I am thinking that as IAM is a global service which defaults to us-east-1, perhaps that region is implicit unless overridden.
