Hello @viren76,

It seems this error may be related to AWS itself, did you change your credentials or your private/public keys? We can't do much to recover your instance remotely, I suggest you get in touch with AWS support so they can help you recover access to the machine.

Regards,

I did not change credentials. When this problem started I was able to login
to the server but I was getting frequently disconnected. I thought it was a
temporary ISP network connectivity issue but now I cannot login at all. I
also see the following errors on console logs while port 80 and 443 are
open and the website was up Yesterday.

I don't know what is wrong with installation now because my site was up and
running fine before I lost access.
I have also raised a ticket with AWS Support for server access issues.

Hello @viren76,

I haven't seen any cases similar to this before, but the line Started Apply the settings specified in cloud-config. suggests a configuration change in AWS

Without ssh access to the console we can't start debugging the issue, let's see what AWS Support can do to re-establish it before we can move forward.
