GVim Windows: :Copilot setup fails with E-32603: Request signIn failed #281
Description
Hello there,
I am on Windows, using gVim 9.2. I followed the installation instructions in README.md to install the copilot plugin. When running :Copilot setup within vim, I get the following error message:
Copilot:E-32603: Request signIn failed with message: Response content-type is missing (status=200)
The only point where I deviated from the readme instructions during the installation is that I cloned the plugin repo at a different location
%USERPROFILE%/vimfiles/pack/plugins/start/copilot.vim
instead of
%USERPROFILE%/vimfiles/pack/github/start/copilot.vim
What do you think I could be doing wrong?

Having a similar problem - freshly installed Arch System:
Build type: RelWithDebInfo
LuaJIT 2.1.1774896198
return { { "github/copilot.vim", lazy = false, init = function() vim.g.copilot_no_tab_map = false end, }, }dericsso commentedon May 10, 2026
Exact same problem, i also used AstroNvim same as @LStoneyy
Downgrading nodejs seems to fix the issue, as mentioned here, i downgraded mine to node@24 using mise

I can confirm that downgrading node to version 24 works, thanks @dericsso for the hint!
