Node-RED running fine but suddenly shuts down and loses connection

I set up Node-RED on an EC2 instance using Docker and installed it via the command line. It was working fine, and I could access it without any issues for the past few days. However, today, it suddenly lost connection, and I'm unable to access it. I need help troubleshooting this issue.

You are going to need to supply a LOT more information before anybody can help.

e.g. (this is just a starting sample)

  1. Can you still log into the EC2 machine?
  2. Is the docker container still running?
  3. What exactly do you mean by "I'm unabled to access it"? Do you mean access the Node-RED editor or something different e.g. a deployed Node-RED Dashboard?
  4. Supply the logs from the container (do not post screenshots, post the actual text and surround it with tripple back ticks so it's formatted correctly)

Where are the logs in the screenshot from? They are not from core Node-RED, so may be some node you have installed?
