Hi, I've installed everything like here [https://www.youtube.com/watch?v=FImTcHECpC0](https://www.youtube.com/watch?v=FImTcHECpC0)

When I paste [http://localhost:5601/](http://localhost:5601/) to browser, `{"statusCode":500,"error":"Internal Server Error","message":"An internal server error occurred"}` occured

Here is a terminal message:  
` TypeError [ERR_INVALID_CHAR]: Invalid character in header content ["kbn-name"] at ServerResponse.setHeader (_http_outgoing.js:473:3) at Object.internals.writeHead (/Users/User/kibana-7.8.0-darwin-x86_64/node_modules/hapi/lib/transmit.js:323:21) at Object.internals.transmit (/Users/User/kibana-7.8.0-darwin-x86_64/node_modules/hapi/lib/transmit.js:105:15) at Object.exports.send (/Users/User/kibana-7.8.0-darwin-x86_64/node_modules/hapi/lib/transmit.js:32:25)`

I'm not modifying anything.  
Does anyone have any idea what's going wrong?

MacOS, 10.14.6  
Safari and Chrome browsers

Thanks a lot

If `server.name` not specified in the `kibana.yml`, it falls back to `hostname` provided by OS. Probably it contains some invalid characters. Would mind configuring `server.name` in `kibana.yml` config file explicitly? For example:

```yml
server.name: "my-kibana"

```
