How to ssh from one host to another host using robot framework?

Question

I have a situation where I need to, using robot framework, ssh to host1 and then to host2 from my local mac machine, as there is no route to host2 directly. I tried opening second connection after opening the first connection but this didn't work.

Test nested ssh connections
    Open Connection     ${host1}
    Login               ${host1-user}      ${host1-pw}
    ${output}=          Execute Command     hostname
    log to console      ${\n}${output}
    Open Connection     ${host2}    #there is no pw
    ${output}=          Execute Command     hostname
    log to console      ${\n}${output}

output:

Open Connection And Log In                                ...
host1
 14:17:59 up 44 days, 18:13,  1 user,  load average: 0.00, 0.01, 0.05
Open Connection And Log In                                | FAIL |
Connection not open

Ican't figure out why second connection doesn't open. Is there a solution to this problem? Any help is appreciated.

After opening connection to first host, you can simply use Write, Read, Read Until keywords to login to second host. The keyword will look something like: (you can use variables, I am using hardcoded values for ip, username, password)

Test nested ssh connections
    Open Connection     ${host1}
    Login               ${host1-user}      ${host1-pw}
    Write    ssh [email protected]
    Read Until    password:
    Write    user123
    Read Until    $
