Exception trying to fetch the data from the second Kinesis stream located in another AWS region

Hello.

## Description
The first input was configured to fetch logs from the Kinesis stream in the `us-east-1` AWS region and working now. Then I was able to configure the second input and even received a message to pass the configuration check. But after that no more messages have been received via this input. Second input configuration is the same as the first one except it's located in another `eu-west-2` region .

## Steps To Reproduce

1. In the region `us-east-1`:
* Create EC2 Autoscaling Group (min=1, max=1).
* Create ECS cluster
* Attach EC2 instance to the cluster.
* Create Graylog ECS Task and configure task role to fetch logs from any Kinesis stream.
* Start a ECS Service to run Graylog container on the single EC2 node.

2. Still in the region `us-east-1`:
* Create CloudWatch Log group.
* Create Kinesis stream (1 shard, 24h retention).
* Create CloudWatch subscription.

3. In the region `eu-west-2`:
* Create CloudWatch Log group.
* Create Kinesis stream (1 shard, 24h retention).
* Create CloudWatch subscription.

4. Login into Graylog and configure 2 `AWS Kinesis/CloudWatch` inputs from both aforementioned Kinesis streams.

5. Only the first input will be working. The second throws exception:
