I have opened a support case.
As an AI language model, I don't have access to real-time data or specific information about your email service. Therefore, I cannot provide a definitive answer regarding the status of the email service or any ongoing issues.
However, receiving a "454 Temporary authentication failure" error typically indicates an issue with the authentication process when sending emails. It could be related to incorrect login credentials, misconfigured authentication settings, or temporary issues with the email server.
To troubleshoot the problem, here are a few steps you can take:
-
Verify Credentials: Double-check the login credentials (username and password) you are using to send emails. Ensure they are correct and up-to-date.
-
Review SMTP Settings: Check the SMTP (Simple Mail Transfer Protocol) settings in your email client or application. Ensure that the server address, port, and authentication method (such as username/password or API key) are configured correctly.
-
Check Firewall and Antivirus: Confirm that your firewall or antivirus software is not blocking the email service's connection. Temporarily disabling these security measures (if safe to do so) can help identify if they are causing any conflicts.
-
Contact Email Service Provider: Reach out to your email service provider's support team or consult their documentation or status page to see if there are any known issues or maintenance activities affecting the email service.
By following these steps and contacting your email service provider for assistance, you should be able to gather more information about the "454 Temporary authentication failure" error and resolve the issue.

We are experiencing the same issue since June 10th 7PM CET. Our monitoring checks the SMTP authentication every minute and we get errors at least once per hour. SES is in eu-central1 and is set to production mode. Mail volume is low.
Kind regards, Kristian
We also started experiencing this on June 10th 21pm CET in eu-central-1 We get errors randomly. 1 in every ~20 emails fails with the mentioned error message.
We have the same problem beginning (our jobs are strating at 00:00, so it could be that the problem occurred even earlier) on June 11th 00:00 CET in eu-central-1. Also occurring randomly.
