Error message

failed to create cloud instance for server %s(%s): %w

What it means

In buildCloudGroup, NewCloudInstance rejected the server (duplicate ID, nil nodeMap entry issue, or invalid status) while mapping a Scaleway server to a kops CloudInstance. The server name and ID pinpoint the offending machine in the group being built.

Solutions

1. Check for duplicate server IDs in the Scaleway server group
2. Verify the server still exists and is not in a transitional state
3. Remove or recreate the offending server if its state is inconsistent
