[BUG] Agent stuck loading

[the-isz]

Describe the bug
Running the command :TabnineAgent opens a window (the WebView) in which "// Loading Tabnine //" is shown together with an animated icon.
Occasionally the window flashes white, but nothing else happens.

To Reproduce
Steps to reproduce the behavior:

1. Install tabnine according to the README
2. Confirm that tabnine works by editing and observing suggestions
3. Open the agent via :TabnineAgent

Expected behavior
The WebView should finish loading so that it can be used to communicate with the agent.

Version Info:

• OS: Ubuntu 22.04.5 LTS
• Neovim version: v0.12.1
• Installed Tabnine Binaries: 4.334.0
• Active Tabnine Binaries: I don't have a .active file.

Additional context
I'm using the Tabnine Enterprise edition.
I would be happy for any way to analyze the problem, because I can't see any error messages that I could google for.

I am experiencing the same issue with MacOS with the enterprise edition. The configuration used is the one from the example:

local tabnine_enterprise_host = "https://tabnine.customer.com"

return {
  {
    "codota/tabnine-nvim",
    build = "./dl_binaries.sh " .. tabnine_enterprise_host .. "/update",
    -- Setting lazy to false ensures the binary starts and handles the 308 redirect immediately
    lazy = false,

    config = function()
      require("tabnine").setup({
        disable_auto_comment = true,
        suggestion_color = { gui = "#808080", cterm = 244 },
        codelens_color = { gui = "#808080", cterm = 244 },
        codelens_enabled = true,
        debounce_ms = 800,
        dismiss_keymap = "<C-]>",
        accept_keymap = "<Tab>",
        exclude_filetypes = { "TelescopePrompt", "NvimTree" },
        log_file_path = nil, -- absolute path to Tabnine log file,
        tabnine_enterprise_host = tabnine_enterprise_host,
        ignore_certificate_errors = false,
      })
    end,
  },
}

Version Info:

• MacOS: Tahoe 26.5
• NeoVim: v0.12.2
• Tabnine Binary: 4.334.0
• Active Tabnine Binaries: I don't have a .active file.
