Why can't the IBM Cloud Object Storage bucket be found?

A flow log collector requires an IBM Cloud Object Storage bucket to be created and accessible. If you see the error log with message ID is.flow-log-collector.00003E, the bucket does not exist, or is no longer accessible. The flow log collector cannot publish data to the IBM Cloud Object Storage bucket.

To avoid lost data, create an IBM Cloud Object Storage bucket within the next 24 hours to correct this problem.

The flow log collector lost connection to an IBM Cloud Object Storage bucket: is.flow-log-collector.00003E: Cloud Object Storage bucket <BucketName> was not found

A bucket that is associated with a flow log collector was deleted, or is not accessible by a flow log collector.

Follow these steps to resolve this issue:

Create an IBM Cloud Object Storage bucket with the same <BucketName> specified in the error message. To create an IBM Cloud Object Storage bucket, see the IBM Cloud Object Storage ordering page.

The IBM Cloud Object Storage bucket must be a single-region bucket in the same region as the target resource. Additionally, it is recommended that you secure the bucket through IAM access groups and audit logging.
Check to make sure that you defined an authorization between the flow log collector and the IBM Cloud Object Storage bucket so that the flow log collector can publish data. To define an authorization, use the following steps:
- In the IBM Cloud console, click Manage > Access (IAM).
- Select Authorizations from the navigation pane.
- Click Create.
- For Source service:
  - Select VPC Infrastructure Services. Then, select Services based on attributes.
  - Select Resource type. Then, select Flow Logs for VPC.
  - Select Source resource instance and choose an option.
- For Target service:
  - Select Cloud Object Storage. Then, select Services based on attributes.
  - Select Service instance and choose an option.
- For Service access, select the Writer role.
- Click Authorize.
