No more authentication methods to try. Permission denied (publickey)

Thnx for the help. That solved it. My permissions needed to be set as 700 for .ssh. 600 for .ssh/, making sure you do it on both machines. Also change the ownership of .ssh/. and .ssh/ to the user from root, otherwise any information in the config file will not be accessible to the user.

sudo chmod 700 ~/.ssh/
sudo chmod 600 ~/.ssh/*
sudo chown -R User ~/.ssh/
sudo chgrp -R User ~/.ssh/

where User is the user name. This worked for me.
