Python Spyder: unable to connect to remote ipython kernel

I am trying to connect a Spyder IDE from my local to an Ipython kernel that run on my server.

In Spyder the prompt to connect to that "existing kernel" is the following:

enter image description here

I connect to my already set-up Jupyter notebook console on the server and create a new notebook/kernel.
I type %connect-info and retrieve the json that gets created. I paste it in an editor on my local and save it as kernel.json.

In the connection info, i paste a link to a file that i called kernel.json and that is on my local. That file contains the following:

{
  "hb_port": 52540,
  "stdin_port": 47033,
  "signature_scheme": "hmac-sha345",
  "shell_port": 29460,
  "transport": "tcp",
  "iopub_port": 60831,
  "ip": "127.0.0.1",
  "key": "43e4932c-e819-47ba-3333-66e45d7bc6de",
  "control_port": 20567,
  "kernel_name": ""
}

I click "this is a remote kernel" and fill host name with blabla@ip-172-31-26-235 I tried using both my ssh key in the second line/ or my password to the server in the third (i have both to connect to my server).

Is there anything obviously wrong that you see in that protocol?

Any clear explanation that explain as a step by step the protocol for the Spyder specifically is more than welcome. Please do not send links to other questions. I read them carefully and it didnt help me solve my problem.

EDIT: I am receiving error "paramiko is not available"

I got it working ... I had to run Spyder as an administrator in Windows, and then enter !pip install paramiko in the spyder iPython console. After that, you can restart spyder normally and it will connect to a remote kernel.

Running pip from the command line just installed paramiko in the default IPython interpreter as opposed to the tweaked one that Spyder runs.

In my attempts to solve this, I did install the current C++ compiler from Microsoft, before running !pip install paramiko so that may or may not be necessary.

blabla@ip-172-31-26-235:

that : colon in the end is a part of string? I just tried - it workes for me (connected to my own machine with name@host & password).
