Ionic 3 Cordova Resource Network Connectivity Error-CodePudding

I want to change my default icon and splash screen, so I replaced my old icon.png and splash.png files with new ones and ran the below command

ionic cordova resources android

It fails and gives the below message

√ Collecting resource configuration and source images - done!
√ Filtering out image resources that do not need regeneration - done!
× Uploading source images to prepare for transformations - failed!
[ERROR] Network connectivity error occurred, are you offline?

        If you are behind a firewall and need to configure proxy settings, see:
        https://ionicframework.com/docs/cli/configuring.html#using-a-proxy

        Error: getaddrinfo ENOTFOUND res.ionic.io res.ionic.io:443
            at errnoException (dns.js:50:10)
            at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:92:26)

What is causing this issue?

Note: I am not behind any firewall or using a proxy.

It looks like the ionic server is not responding. In that case, you can use an NPM package cordova-res which allows you to generate resources offline. Works for Android as well as iOS.
