SSH Bookmark Issue

Question

Hi all, 
 I'm trying to setup an SSH bookmark to log me into the CLI of my Cisco SG300 switch by providing the username and password. When I launch the bookmark, it starts to establish the session and then I get a popup with the following: 
 "No RSA host key is known for [IP of switch] and you have requested strict checking. Host key verification failed." 
 The bookmark is setup as follows: 
 Type: SSH 
 URL: LAN IP of switch (VLAN1 SVI) 
 Port: 22 
 Username: admin username 
 Password: admin password 
 Automatic Login: YES 
 Authentication Method: PASSWORD 
 Public Host Key: Public RSA Key copied from the switch's SSH Server details. 
 I've probably got the wrong key or something, does anyone have any ideas where I've gone wrong?

Had a similar problem but then worked it out by copying the entire code like this with ssh-rsa and all: 
 ssh-rsa AA..................................................1

Kudos to WajdiAyach for his PM with the solution... 
 When I was copying the SSH key from the switch, I used the whole thing including ---- BEGIN SSH2 PUBLIC KEY ---- 
 The XG only wants to see ssh-rsa and then the key. Same also works for a Ubiquiti Cloudkey I have that uses ecdsa-sha2-nistp256 and then the public key. 
 I can now successfully browse to my public IP, log into the user portal and launch an shh bookmark to get a terminal to access these devices. 
 Thanks again WajdiAyach !
