Describe the bug

When trying to install a coc.nvim extension with the command CocInstall coc-name-of-the-extensions it fails installing it. I have tried installing other extensions, but it fails always, and I have tried reinstalling coc.nvim, but without success

Reproduce the bug

We will close your issue when you don't provide minimal vimrc and we can't reproduce it

• Create file mini.vim with：

  set nocompatible
  set runtimepath^=/path/to/coc.nvim
  filetype plugin indent on
  syntax on
  set hidden

• Start (neo)vim with command: vim -u mini.vim

• Run :CocInstall coc-kotlin

It's your network issue, ENETDOWN means the network is down.

[giovannigiordano]

I don't want to spam, but my network works well, I don't have any problems navigating on the web or downloading other stuff, I only have problems when installing coc extensions, even trying to reinstalling coc works, so, how it can be the network?

[fannheyward]

As you can see in logs, coc begins to download the extension from npmjs.org, with progress, then enetdown error, I can't reproduce this, this error is properly caused by network.

Could be some other software that closed the network connection, you can try to use proxy.
