I was able to ssh
ssh -i "key_1.pem" [email protected] -v
into this new instance, however after I attached the backup volume, I get the same problem as I did with the old instance, same error message too. I tried with different users bitnami, ec2-user and root.

When I go onto the public ip, I see my old site showing. This must mean the backup volume was attached properly right? I ve read alot of forums saying the problem could be in mounting the volume, and proposed changes the the fs, however I cant ssh so I am stuck outside the server. I have also tried alot of methods suggested by other forums. Yes the key is correct, and I've tried with both the old and new key.
I am an amateur at developing so please go easy, and have been stuck on this for an embarrassing amount of time. Many thanks!
