`:PlugUpdate`/`:PlugInstall` freezes NeoVim

[hood]

Basically running :PlugUpdate/:PlugInstall hangs my NeoVim instance. :PlugClean, :PlugStatus and :PlugDiff run fine. When NV hangs, the only way for me to get out of it is by killing the process. I’ve tried removing plugins and loading only one of them (rotating the one left, to avoid picking the offending one, if any) but the problem persists. I’ve tried building NeoVim from an older commit (all the way back to versions from ~6 months ago), but the problem is still there. Even running nvim --headless -c ‘PlugUpdate’ makes the process freeze.

Is this the first time you use vim-plug, or did this happen suddenly after using it for a while?

I've been using the plugin for years. Nothing major that I can recall changed in my setup when the issue started occurring.

Hm... Your github access seems restricted.

[jdssl]

@Shougo I solved the problem with my internet provider, thanks!!!

Found out that doing Ctrl-C revives the process if i hit it early enough. 🤷

This stopped happening ofr some reason, closing the issue as nobody else seems affected anymore.
