Cannot connect to EC2 instance

0

Since 8am this morning one of our ec2 instance became unresponsive. We could not connect to the websites hosted on it, and we could also not connect to the databases on it, and also we could not ssh to it anymore. We did not perform any maintenance on this server or changes anything related to the instance

In addition, you can:

1/ Check the Security Group whehter the inbound rules is correct or not.

2/ Check the Monitoring and see whether it's out of resouces (eg. CPU).

Im wondering if the EC2 is non responsive will it advisable to detach this volume from it and attach it to a new instance we spin up? We would then just reconfigure all the site urls on the new server

  • Did you try rebooting the instance?

    Did you take a look at AWS Systems Manager / Node Management / Session Manager? Check if you have any Sessions there you can Terminate and start a new one. And take a look at your Preferences for your sessions that might be blocking you to access your EC2 instance.
