com.netflix.zuul.exception.ZuulException: Forwarding error #738

Closed daz1761 closed 1 month ago

daz1761 commented 4 years ago

We are facing a problem (White Lable Error Page) with a basic out the box ASP.NET Core Web API that is running in a Docker Container that has been created with the Steeltoe Initializr on Ubuntu Server 18.04 (on the same network) with Zuul and Eureka, but strangely it works locally on Docker for Windows and Ubuntu Desktop with Docker on different machines. We also have a test Spring Boot Web API that works both locally, and on Ubuntu Server.

{
 ........,
  "spring": {
    "application": {
      "name": "dotnet-client"
    }
  },
  "eureka": {
    "client": {
      "serviceUrl": "http://eureka:9001/eureka/",
      "shouldFetchRegistry": false,
      "shouldRegisterWithEureka": true,
      "validateCertificates": false
    },
    "instance": {
      "port": "8099",
      "ipAddress": "ip_of_ubuntu_server",
      "preferIpAddress": true
    }
  } 
}

Here is the stack trace:
