${RemoteServer}= openconnection 127.0.0.1 port=2123
login 127.0.0.1 gfi
${username}= Executecommand pwd
But i am getting error as authentication failed

This is first time i am using SSHLibrary .Does it require any preconditions to use SSHLibrary.
Can someone help how to solve authentication failed.

You have to take a look at the arguments for SSHLibrary - Login keyword.
As seen in the documentation Login first argument is username.
However, in your code you give 127.0.0.1 as username.
login 127.0.0.1 gfi
And I assume that is not the username.
You can also see this in the log message, that it try to login 127.0.0.1:2123 as 127.0.0.1.
INFO : Logging into '127.0.0.1:2123' as '127.0.0.1'.
If you update the code and call login keyword with username and password as expected, it should run fine.
login <username> <password>
