FetchError: request to https://api.expo.dev/v2/sdks/49.0.0/native-modules failed, reason: read ECONNRESET error in running react native

Question

I have an application file of react native that was running fine in vs code before but now whenever I tried to run it gives this error. I try to run it by PS C:\User\Desktop\ReactNativeApp> npx expo start

Starting Metro Bundler

`FetchError: request to https://api.expo.dev/v2/sdks/49.0.0/native-modules failed, reason: 
 read ECONNRESET

I have tried restarting and even create a new project but it is giving the same error. How can I do to resolve this error?

Answer 1

Start your server with

npx expo start -c

inside your terminal

-c is short for --clear

Answer 2

This problem is probably a network problem.

1. Parse this (api.expo.dev) domain name and get the IP address.
2. Edit hosts file

$ vim /etc/hosts

3. Add a line

$ 104.18.4.104 api.expo.dev

4. If you are using proxy, execute these two commands.

$ export HTTP_PROXY=http://your_proxy_address:your_proxy_port
$ export HTTPS_PROXY=http://your_proxy_address:your_proxy_port
