In zuul 2.x sample demo, a request routing to nginx-backend http service always got 404 error

[whbg]

Condition: 1.disable eureka, and then 2.choose ConfigurationBasedServerList

We found this error was relation to 'Host' header forward to real service. Or i did incorrect configuration(see below bold line)?

For eureka clients running in eureka server, it needs to connect to servers in other zones

Don't register locally running instances.

Which host header are you getting on your backend?

[whbg]

configuration is , api.ribbon.listOfServers=http://xx.com:80 backend Host header is Host:localhost:7001(it should be Host:xx.com:80)

[artgon]

That's not how proxies are supposed to behave. You have to maintain the host header from the original request otherwise your service has no idea where the request came from.

[liangGTY]

I think it's better if the proxy overrides the host header to get the host from ribbon.listOfServers? @artgon

[wongcoekfai]

And so? how to fix this problem?

[SMakhrov]

I have the same problem. @artgon please help to solve this.

[artgon]

If you want to change the outbound host header, you can add a filter that modifies the inbound request headers.
