Error installing the plugin through bower, who faced it?

Question

JavaScript

Hi guys, I've been suffering for the second day. I don't know what the problem is. Google didn't help.
There is a vps server on Ubuntu, LAMP hangs, Iptables+fail2ban.

1. Installed nodejs
   

apt update
apt install nodejs

Installed npm

apt update
apt install npm git-core

Next
ln --s /usr/bin/nodejs /usr/bin/node
, I installed bower.
npm install bower -g
Everything fell perfectly.
when installing, for example, jquery via bower, it gives the following error

bower retry         Request to https://registry.bower.io/packages/jquery failed with ETIMEDOUT, retrying in 1.6s

there is no proxy. Can anyone come across

Answer 1

https://www.npmjs.com/package/jquery
why bower?
