Yarn - There appears to be trouble with your network connection. Retrying

Question

I have been trying to do the quickstart guide for react native, but kept getting this error

There appears to be trouble with your network connection. Retryin         


        

Answer 1

I encountered this error while attempting yarn outdated. In my case, a few of the packages in my project were hosted in a private registry within the company network. I didn't realize my VPN was disconnected so it was initially confusing to see the error message whilst I was still able to browse the web.

It becomes quite obvious for those patient enough to wait out all five retry attempts. I, however, ctrl-c'd after three attempts...

Answer 2

The large package involved often can be Material Design Icons.

Check if you make use of the Material Design Fonts material-design-icons in your package.json and remove it!

material-design-icons is too big to handle and you should only use material-design-icons-fonts if you only need them.

Answer 3

This happens when your network is too slow or the package being installed is too large, and Yarn just assumes it's a network problem. Try increasing Yarn network timeout:

yarn add <yourPackage> --network-timeout 100000

Answer 4

1. Could be that your network speed is too slow and timeout is relatively short, you can set yarn install --network-timeout=30000
2. If you still have the error, could be solved by proxy, vim ~/.yarnrc and add useful proxy setting.

Answer 5

I got this issue because I was working within my company internal network and proxy needed to be set.

$ yarn config set proxy http://my_company_proxy_url:port
$ yarn config set https-proxy http://localhost:3128

example $ yarn config set https-proxy http://proxy.abc.com:8080

Answer 6

Simple working solution (right way of doing it):

Looks like yarn was trying to connect via a proxy. The following worked for me:

npm config rm proxy
npm config rm https-proxy
