Content is not synced to Jupyter

[bverhagen]

The content in my Neovim buffer is not synced to the Jupyterlab instance I have open.

Steps:

1. My jupyterlab runs on a remote server. I installed Neopyter and in the settings I choose the defaults (host 127.0.0.1, port 9001)

2. I installed Neovim extension.

When I open test.ju.py and run :Neopyter status, I get what I should get as @AbaoFromCUG mentions in #15 :

==============================================================================
neopyter:                                                                   ✅

neopyter: config ~
- {
    auto_attach = true,
    auto_connect = true,
    file_pattern = { "*.ju.py" },
    filename_mapper = <function 1>,
    highlight = {
      enable = true,
      mode = "separator"
    },
    injection = {
      enable = true
    },
    jupyter = {
      auto_activate_file = true,
      partial_sync = false,
      scroll = {
        align = "center",
        enable = true
      }
    },
    mode = "direct",
    on_attach = <function 2>,
    parser = {
      python = {},
      r = {},
      trim_whitespace = false
    },
    remote_address = "127.0.0.1:9001",
    textobject = {
      enable = true,
      queries = { "cellseparator", "cellcontent", "cell" }
    }
  }

neopyter: version ~
- neovim plugin(neopyter@0.3.2) status: active
- jupyter lab extension: don't connect

neopyter: status ~
- attach=ready, connect=syncing

- file                           attach     connect    remote_path
- * gpu.ju.py                      true       false

Trying commands like:

:Neopyter execute kernelmenu:restart

returns an error:

RPC websocket server is listening, but without client, can't request [executeCommand]

How can I debug this further?

Sorry for the delayed reply. I had add new section Troubleshooting in README.md,

• you could check port listening status on the host where neovim is located, e.g. lsof -i :9001 on Linux/MacOS or netstat -an | findstr 9001 on Windows
• Could your provides more information of your browser's console tab? e.g.:
  

I guess the jupyter lab's extension(neopyter) can't connect the websocket server (the neovim hosted), ws://127.0.0.1:9001

i am having the same issue, all of these issues were closed without a solution, what is going on?

cannot connect to ws://127.0.0.1:9001
