No: the -via option of vncviewer is a short way to setup an ssh tunnel
to the SERVER running Xvnc (vncserver).

I suspect that you have specified the 3022 port fo connect to euripide
in your ~/.ssh/config file.

Can you verify (and undo) that?

Before retrying vncviewer simply test an ssh connection:

Example; ssh -v euripide id

In addition:

  - you have once to setup a vnc passwd on euripide by using the
    vncpasswd command.

  - since you have chosen the 5901 port on euripide, you should tell
    that to vncviewer:

    vncviewer -via euripide :1

  - remmina is not needed for that purpose. You have to edit the file
    ~/.vnc/xstartup to change the session you want.
    Start simple, for example with an xterm

    Restart afterwards the vncserver@:1.service
