I tried reproducing your issue by proxying to a server on localhost, but it worked fine for me when offline. Could you provide more information? Note that we use http-proxy-middleware for proxying, so if there is an issue, it's probably over there.

On _Windows_ you have to use 127.0.01 instead of localhost to be able to work offline.

the same issue with me!,I find in the http-proxy-middleware,there is a error.
in function getProxyEventHandler()
_.get will return undefined instead of a Function type.
But it need a function to listen proxyEvents

Guys, I think "localhost" is resolved with an active connection to the router. Try to replace localhost to 0.0.0.0 in your proxy object like this:
proxy: { '/api': { target: { host: '0.0.0.0', port: 3000, }, secure: false, }, },
