ssh tunneling ec2 -- Permission denied (publickey)

Question

I have a hashicorp consul cluster that is in a private subnet on ec2. I want to access the consul web ui.

I added my key for ssh forwarding as:

ssh-add -k <my_private_key>.pem

I am able to use the following to log into my machines

ssh -A ubuntu@<bastionIP>

However when I try the following command for tunneling:

ssh -i <private_key>.pem -L 8500:10.0.31.163:8500 ec2-user@<bastion_public_IP>

I get the following error

Permission denied (publickey)

the ssh -vvv option output can be found here (IPs obfuscated): https://paste.ubuntu.com/25405193/

Thanks for your help!

Answer 1

Remove any other ec2 private key that is already added in your system.

Then remove rm -f ~/.ssh/known_hosts

then try to connect with running ssh ec2-user@host
