Hello.
Could you tell us a little more about your situation?
Is it correct to understand that the current problem is that public access to RDS is no longer possible?
Or does it mean that you can no longer access your EC2 hosted website?
Is it correct that the website is stuck due to not being able to access RDS from EC2?
If this understanding is correct, is there any error output in the access log or error log when accessing the website?
Also, if there is an error when accessing the website, would it be possible for you to share that as well?

Could you see the screenshot attached to this message? Are you referring to the connection from EC2 to RDS as shown by the screenshot?

Hi Riku Followed these prompts from the Survey Solutions website: https://docs.mysurvey.solutions/headquarters/config/aws-setup/, a server was created on Amazon to host the Survey Solutions application which allowed me to store my questionnaires and collected data. Since the RDS hardware maintenance scheduled on 13 July, I have no longer access to my public DNS (IPv4) nor do my PostgreSQL. The URL does not open anymore.
The hosted website is as follows: ec2-54-85-162-32.compute-1.amazonaws.com Below is the message from Amazon regarding the maintenance: Service RDS Start time July 13, 2023 at 4:51:00 PM UTC+10 Status Completed End time July 20, 2023 at 4:51:00 PM UTC+10 Region / Availability Zone us-east-1 Category Scheduled change Account specific Yes Affected resources 1 Description We are contacting you to inform you that one or more of your Amazon RDS DB instances listed in the 'Affected resources' tab are scheduled to receive maintenance on the underlying hardware between 2023-07-13 06:51 UTC (Thursday) and 2023-07-20 06:51 UTC (Thursday). You can view the scheduled maintenance time and perform opt-in actions on the RDS Console, using the AWS CLI or the AWS RDS API. Single-AZ deployments will be unavailable for a few minutes in the instance's maintenance window.
(Continued)
Multi-AZ deployments may be unavailable for the amount of time it takes a failover to complete, usually about 60 seconds, also in the instance's maintenance window. For more details refer to the email sent to your system account. Please review the maintenance window or take appropriate opt-in action for each affected DB instance to minimize the impact of this maintenance on your application. If you have any questions or concerns, contact AWS Premium Support. http://aws.amazon.com/support
Is it possible to check the access log and error log of IIS installed on EC2? Also, could you share what kind of error you get when connecting from EC2 to RDS with a command?
Hi Riku
Could you help me in finding the access log and error log of IIS installed on EC2?
Thank you for your reply. Since it is a Windows instance, is it possible to connect to the instance with an RDP connection, etc.? I think that the log is output to the following folder by default.
I saw the screenshot, but I can't tell if it's possible to connect based on that alone. For example, I think it is necessary to check whether the security group settings used in RDS are configured correctly.
