Ec2 instance became repeatedly inaccessible despite multiple reboot attempts.

0

Hello, One of our ec2 instance with centos 7 running in region ap-south-1 with LAMP application. On 1st of July 2024 around 8:30 AM IST onwards got inaccessible all of sudden. as there was no load on the server. Initially when we rebooted the server it got up status also at that time 2/2 checked pass, but again it got inaccessible. When we rebooted the server again instance state showing running but the status check get stuck in initialising for more than 30 minutes. After that if we reboot the instance again it gets up and status check shows in 2/2 checked pass but again after 2-3 minutes it gets inaccessible.

This was happening repeatedly, we tried stop all the services running inside, still its getting inaccessible repeatedly. Can we check is there any issue in underline hardware or something else.

Hello.

Can we check is there any issue in underline hardware or something else.

AWS re:Post cannot be used to confirm whether there is a problem with an AWS physical server, etc.
I think you will need to contact AWS Support regarding "Account and billing".
Inquiries under "Account and billing" can be made free of charge.

After that if we reboot the instance again it gets up and status check shows in 2/2 checked pass but again after 2-3 minutes it gets inaccessible.

Have you checked the system logs of the EC2 instance?
There may be some errors output to the log.

Also, check to see if there are any problems with CPU usage or memory usage.

    Stopping and starting an instance also generally causes it to be placed onto a new host, so that would rule out underlying hardware issues.

    Thanks, for your reply. I have checked system logs of the ec2 instances but didn't found anything suspicious on the server. Also i have raise the ticket, waiting for their reply.
