Setting ltex.languageToolHttpServerUri for ltex-ls does not seem to be working

[cristobaltapia]

Description

I have started a languagetool server in my homeserver. The server works correctly, as I could corroborate by running curl --data "language=en-US&text=a simple test" http://192.168.1.103:8010/v2/check. However, when adding the option ltex.languageToolHttpServerUri=http://192.168.1.103:8010/ ltex-ls does not perform the check.

Neovim version

NVIM v0.9.0 Build type: Release LuaJIT 2.1.0-beta3

Nvim-lspconfig version

30a232052b3e1c0c51d190d5f5a12ad9b42c5ebc

Operating system and version

Archlinux

Affected language servers

ltex-ls

Steps to reproduce

1. Open a file with text to check
2. Wait for ltex-ls to check the text

Actual behavior

No grammar correction is made.

Expected behavior

The grammar corrections should be performed in the homeserver.

Minimal config

nvim_lsp.ltex.setup {
    cmd = { "/usr/bin/ltex-ls" },
    settings = {
        ltex = {
            language = "en-US",
            languageToolHttpServerUri = "http://192.168.1.103:8081/",
        },
    },
}

So is this an ltex-ls problem then? I cannot make much sense of these java errors :)
