Permissions 0550 for 'XXXXXXXXXXXXX/.ssh/id_rsa' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
Load key "XXXXXXXXXXXXXX/.ssh/id_rsa": bad permissions
[e-mail]: Permission denied (publickey).

Solution ： Linux: Modify the key pair file attribute to 700/500/400

chmod 700 XXXXXXXXXXXXX/.ssh/id_rsa*

Windows: In the key pair file attribute security option , Change the file control permission to only the owner of the file can control
