Elastic Beanstalk EC2 instance asking for login?

Hello there!

since yesterday an EC2 instance created by Elastic Beanstalk started to failing. Basically, it is attempting to initialize, wait for 2 minutes and fails, repeating the cycle over and over again.

I tried to get some logs from that instance and there were none. The only thing that I could grab was a screenshot (Through the management console) which shows the Linux version being used, the IP address and a prompt asking for a login !?

Trying to find any information about the possible causes, I wasn't able to find any. At least, nothing that could explain why this EC2 managed resource started to fail this way or even what login is expected.

I have also checked permissions and the "general stuff" making sure that all is in place, but nothing is popping out that could give me a hint.

Important to say that I have several other Beanstalk instances up and running but this one is the only one that suddenly stopped working.

Any guidance will be really appreciated.

Regards
