This is the first thing to check. Also check the permissions all the
way up to the root of the file system. $HOME/.ssh and $HOME must be
owned by you, and $HOME must be no more open than mode 755. /home and /
must be owned by root and no more open than mode 755. OpenSSH will
reject keys if the file system permissions do not meet this minimum.

If permissions are good then check your key types. DSA keys are dead
and are rejected by OpenSSH. Generate and use ED25519 or RSA keys.

If key types are good then check key lengths. Too-short keys may be
rejected. If this is the case then you will need to generate new keys
of sufficient length.
