Issue

Not able to connect via SSH-Key pair authentication
Using the same private key to connect from other server, able to authenticate and connect
Tried setting public key auth from client end exclusively but it failed with same issue.
```
# ssh -vvv -o "PreferredAuthentications=publcikey" <user>@<IP>
```
Debug logs does not shows any logs pointing to issue with client system or server system. Connection just gets close with warning "Connection blocked because server only allows public key authentication. Please contact your network administrator." on client end.
