How to fix the ssh key comment length.
If the SSH comment line extends past the keys body it can cause issues with connecting using SSH Key.
Resolving the problem
Be sure to truncate the comment line. If the key looks similar to this:---- BEGIN SSH2 PUBLIC KEY ---- Comment: '2048-bit RSA, converted from OpenSSH by AR@us.silverpopsupport.com' AAAAB3NzaC1yc2EAAAABIaQWAAQEA1cyNRUxjdnG26RAo01mUr7R+myjRBOdCdOVmFyTc gLkvaJ5xwnxttPmX3Gs7abcd4z94xz5X9E8hf57G6boZQOUUsw3wO5iSWQv2VZdDtbIyEIP L89Cc3kJTWffoiSYEYWsB5JARcO0keFHT0Fef830/nvhzax71TKUWgHMyRY0P6oAI2U7vm u/SFmFS4Szqd/mkF7Kfu/6Kreweschhy+T0JURhLxrj3aXJyHBBe6hqWNQsbivLJO3fPT7Wf 9IdP2jzYRK/uCv46C7SKfZWVzYuO1dbChqrU+KdYB1ONiv+Goq7B66GQnFwbQRxCgRm6TZ 7nWVkkiKuqMJAXQo5p7Q== ---- END SSH2 PUBLIC KEY ----
Change it as follows
---- BEGIN SSH2 PUBLIC KEY ---- Comment: '2048-bit RSA, AR@us.silverpopsupport.com'

You do not need to have all that extra information within the comment.
