Hi,
When I try to login to the router using ssh like,
ssh admin@10.0.10.1
It asks me for a password even though I have saved my rsa4096 public key on the router for pub key based authentication and it denies access even when I enter the correct password in the password prompt.
Running Router OS 7.2 on RB450GX4
