After executing some systemctl commands on our EC2 instance yesterday, the terminal froze and now we are unable to SSH back into the server. The API service we were hosting on this website is also down, and we'd like some assistance getting everything up and running again. I did try a few obvious things, name turning the system off and on again, as well as leaving it off overnight and restarting it in the morning. Still, no luck. Please let us know what can be done.
Hi, you should update the question with the systemctl commands that you used: some may well block access to the system
Most probably, it's a iptables/firewall issue.
Do you have previous snapshot that you can rollback to?
Also, what is the error you are getting please?
