Erro "Fail to request credentials" e "Failed to describe Volume vol-0fbd7fb10faaaeddc Fail to request credentials"

Question

Bom dia, tudo bem ?

Ao acessar de manhã a tela das Instâncias para rebootar o EC2 prod-maasweb-kotlin aparecia a mensagem que estava demorando para buscar os dados do EC2 e após um tempo terminava com a mensagem do primeito printscreen. 
NA hora pedi que o usuário Mateus entra-se na mesma tela e com ele não ocorria o erro. 
Voltei na minha tela e continuava com erro, após alguns minutos, tentei novamente  normalizou.
No momento está funcionando corretamente.
No sábado ocorreu de não conseguir retornar nenhum dado das instâncias. Mas, resolveu rapidamente.
Porque este erro intermitente ?

This error appears to be related to credential issues when trying to access AWS EC2 resources. The error messages "Fail to request credentials" and "Failed to describe Volume vol-0fbd7fb10faaaeddc Fail to request credentials" indicate that your AWS session was having trouble authenticating properly to perform the requested actions.

The intermittent nature of this issue could be caused by several factors:

1. Temporary credential expiration: AWS temporary credentials might have expired during your session, causing the authentication failure. After some time, new credentials may have been automatically obtained, resolving the issue.

2. Authorization issues: Your IAM user might have permissions that are close to their limits or that have conditional access policies that sometimes prevent certain operations.

3. Network connectivity problems: Intermittent network issues might have prevented proper authentication with AWS services.

4. Session timeout: Your AWS Management Console session might have timed out, requiring re-authentication.

The fact that another user (Mateus) could access the same resources suggests that this was likely specific to your session or credentials rather than a service-wide issue.

To prevent this in the future:
- Try refreshing your browser or signing out and back in when you encounter these errors
- Ensure your IAM permissions are properly configured for the resources you need to access
- Check if there are any network issues that might be affecting your connection to AWS services

If this continues to happen frequently, you may want to contact your AWS administrator to review your IAM permissions and ensure they're properly configured for the EC2 and EBS resources you need to access.
