Observations:

  • I can ping http://localhost:8080/ide/api/
  • {“rootResources”:[{“path”:“project-template”,“regex”:“/project-template(/.)?“,“fqn”:“org.eclipse.che.api.project.server.ProjectTemplateService”},{“path”:“event-bus”,“regex”:”/event-bus(/.)?”,“fqn”:“org.eclipse.che.api.core.notification.WSocketEventBusServer”},{“path”:“/workspace”,“regex”:“/workspace(/.)?“,“fqn”:“org.eclipse.che.api.workspace.server.WorkspaceService”},{“path”:”/machine",“regex”:"/machine(/.)?”,“fqn”:“org.eclipse.che.api.machine.server.MachineService”},{“path”:“/profile”,“regex”:“/profile(/.)?“,“fqn”:“org.eclipse.che.api.user.server.UserProfileService”},{“path”:”/async/{ws-id}“,“regex”:”/async/([^/]+?)(/.)?”,“fqn”:“org.everrest.core.impl.async.AsynchronousJobService”},{“path”:“/recipe”,“regex”:“/recipe(/.)?“,“fqn”:“org.eclipse.che.api.machine.server.recipe.RecipeService”},{“path”:“oauth”,“regex”:”/oauth(/.)?”,“fqn”:“org.eclipse.che.security.oauth.OAuthAuthenticationService”},{“path”:“/stack”,“regex”:“/stack(/.)?“,“fqn”:“org.eclipse.che.api.workspace.server.stack.StackService”},{“path”:”/auth",“regex”:"/auth(/.)?”,“fqn”:“org.eclipse.che.api.auth.AuthenticationService”},{“path”:“/docs”,“regex”:“/docs(/.)?“,“fqn”:“org.eclipse.che.swagger.rest.SwaggerSpecificationService”},{“path”:”/user",“regex”:"/user(/.)?”,“fqn”:“org.eclipse.che.api.user.server.UserService”},{“path”:“/ssh”,“regex”:“/ssh(/.)?“,“fqn”:“org.eclipse.che.api.ssh.server.SshService”},{“path”:”/“,“regex”:”(/.)?”,“fqn”:“org.eclipse.che.api.core.rest.ApiInfoService”}]}
  • Could it really be looking for che-host:8080?
  • I tried creating C:\Users\Eric\AppData\Local\Eclipse Che\vfs\MyFirstWorkspace\etc\hosts with che-host, but that does not seem to work

Hi @kolotyluk. I believe this is a netowrking configuration issue that you are running into. Any chance that you are running Che on a server that has different networks and IP addresses? It looks like Che is having a hard time resolving certain addresses.

You can see more about certain non-standard configurations here. https://eclipse-che.readme.io/docs/networking

You wrote a great issue by the way. Very clear and provides all the background information.
