AWS ruby on rails ssh connection failure

At the first time when i tried to connect to ssh everything was going smooth. At the second time I have tried to connect I have seen a failure like this: Permission denied (publickey). The code that I write is:

ssh -2 -i ~/.ssh/Talkon4key.pem.txt ec2-user@ec2-54-76-37-217.eu-west-1.compute.amazonaws.com

I have also tried

ssh -v -i ~/.ssh/Talkon4key.pem.txt ec2-user@ec2-54-76-37-217.eu-west-1.compute.amazonaws.com

Than I have got this output
