Sometimes you’ll get an error on your ssh client when you’re working with a new ssh key and you’re trying to ssh into the server. To fix permissions that are too open you can do these 2 commands. Most likely you only need to fix the key itself and not the folder.
Fix key files themselves
chmod 600 ~/.ssh/id_you_private_key
Make sure the .ssh key folder is 700
chmod 700 ~/.ssh
