RDS stuck on configuring-iam-database-auth

Hello,

Thanks for reaching out to us on re:Post. I am so sorry to hear the issues with your RDS instance. Hopefully it has been mitigated now.

It looks to me that an internal step in the conversion "might" have been stuck - In these cases we recommend reaching out to AWS Support Team so that the engineers can do a deep dive on the back end instances and take the necessary steps to fix the issue.

I sincerely apologize for the delay in the response to this post. I just saw it now and thought of adding my thoughts on the matter. Have a wonderful rest-of the day!
