Please help me as I am getting “503 Service Temporarily Unavailable” error on getting the data from REST endpoint using Dockerized Kong.

REST service that I am trying to access using Kong is running on my local machine (DESKTOP-2IQC7RC).

Kong Request to add API :

curl -i -X POST   
–url [http://localhost:8001/apis/](http://localhost:8001/apis/)   
–data ‘name=my-api’   
–data ‘uris=/employee’   
–data ‘upstream\_url=http://DESKTOP-2IQC7RC:8080/v1/employee/ping’

Error that I am getting on forwarding the request through Kong:

_**[root@c1c865250782 /]# curl -v -X GET --url [http://localhost:8000/employee](http://localhost:8000/employee)**_

Hi,

With that configuration you are attempting to access `http://DESKTOP-2IQC7RC:8080/v1/employee/ping/employees` (notice the `/employee/ping/employees` part). Is that URL correct? Does it work without using kong, or do you also get a 503 with that one?

Hi, I met the same problem, but if I set the Host in http header, then I can call the api. Do you find another way to call it?
