About "Get Pre Login Banner" keyword

Hello!

I’m unable to get the connection banner using the keyword “Get Pre Login Banner”. if i use the host, like:

${BANNER}= Get Pre Login Banner ${HOST}

I get as error message: “SSHClientException: Unable to connect to port 22 on ”.

And if I do something like this:

Open Connection ${HOST} prompt=${PROMPT}
Login ${USERNAME} ${PASSWORD}
${BANNER}= Get Pre Login Banner

I get: “AttributeError: ‘NoneType’ object has no attribute ‘decode’”.
Both errors happen when i call the banner keyword. Could someone help me with this issue?

Thank you!
