Can't reproduce locally. Maybe it's due to bad cookies on the localhost:8080 domain? Have you tried to open it in an incognito window?

@sodatea thanks but that doesn't make a difference for me

I downloaded a Vue CLI based app from Vue Mastery and same thing

Does any of the replies help? webpack/webpack-dev-server#183

Likely to be a network setting issue but I've no idea why.

@sodatea thanks for the reply and sorry for the delayed response but none of the suggested fixed mentioned there worked for me. Also note that I can open http://localhost for create-react-app based apps so this is something specific to what vue-cli is doing in it's configurations and maybe some incompatibility with mac??? not sure about that second part. But localhost works on my mac book for other things.

@sodatea I'm experiencing the exact same issue as @RyanAtViceSoftware. I'm on macOS Mojave 10.14.6, and am working with Vue cli 4.0.5. I've reproduced the issue in Chrome 78.0.3904.70, Firefox 69.0.3, Opera 62.0.3331.119, and Safari 13.0.3 (14608.3.10.10.1). I also can open http://localhost for other apps and open the ip-based link provided by Vue. The suggested fixes mentioned also did not work for me.

I'm also on macOS Mojave 10.14.6 and @vue/cli 4.0.5, I had the same issue.
I am not entirely sure why I had the issue. For some reason, port 8080 is being blocked.

Anyway, I worked around this by changing the port.

In your vue.config.js, add the following to change the port:

module.exports = {
    devServer: {
        // other config
        port: 8081 // or any other port you wish to use other than 8080
    }
}

After that it worked for me.

Hi! I'm experiencing the same problem on Catalina. Same symptoms, anything can work on 8080 except vue server. lsof -nP -iTCP:8080 | grep LISTEN shows that vue listens to the port but no response is visible in browser

Hi, I'm also experiencing same issue, however, the apps works on 127.0.0.1:8080 and not localhost, in most cases this should at least unblock me but the APIs are configured on localhost:8080. hence need a fix for this.
After changing the port to 8081, the localhost is working.

webpack/webpack-dev-server#183
This issue also looks similar to the webpack-dev-server issue. People seemed to have resolved the issues themselves there, but the provided solutions didn't work for me. Posting it here, as it might help someone else.

I also faced the problem same problem on Mac Catalina, it worked on ip but not working on localhost, then I recognize I did not install vue-cli, after install it working.

I faced that problem, and for me, it worked using chrome rather than firefox.
