Problem description

I am trying to use mason in conjunction with mason-lspconfig to auto-install my language servers upon cloning my config to a fresh machine. This does however not happen until i manually open the :Mason window and let it sit for a couple of seconds or run :MasonUpdate, because it's missing the registry (a :checkhealth confirms this).

Expected behavior

Mason should be fully functional after running setup() and be able to grab the data it needs without requiring user interaction. It should install the packages mason-lspconfig has detected automatically.

Steps to reproduce

1. use this minimal init.lua:

local lazy_path = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"

if not (vim.uv or vim.loop).fs_stat(lazy_path) then
	vim.fn.system({
		"git",
		"clone",
		"--filter=blob:none",
		"--branch=stable",
		"https://github.com/folke/lazy.nvim.git",
		lazy_path,
	})
end

vim.opt.runtimepath:prepend(lazy_path)

require("lazy").setup({
	{
		"williamboman/mason.nvim",
		config = function()
			require("mason").setup({
				ui = {
					check_outdated_packages_on_open = false,
					border = "single",
					height = 0.8,
				},
			})
		end,
	},
	{
		"williamboman/mason-lspconfig.nvim",
		dependencies = { "mason.nvim" },
		config = function()
			require("mason-lspconfig").setup({ automatic_installation = true })
		end,
	},
	{
		"neovim/nvim-lspconfig",
		dependencies = { "mason-lspconfig.nvim" },
		config = function()
			require("lspconfig").clangd.setup({})
		end,
	},
}, {})

... as you can see, the sequencing of the plugins is correct.

2. open Neovim and wait, nothing gets installed. Close and reopen as many times as you like, it stays this way.
3. open :Mason (and wait some time) or run :MasonUpdate
4. reopen Neovim, the package(s), in this case clangd, will now get installed

NVIM v0.10.1

I'm having the same issue (same neovim version).
I'm unable to connect to the remote registry.

Tried switching from NVIM v0.10.1 to an older version (0.9.5) but I could not do that with brew.
Had to pause my neovim learning.
