Connect to Query Client not running on localhost .NET Core

Couchbase Server
1

We are using Couchbase SDK 2.4.7 with dependency injection but cannot connect to the query client. We have a Couchbase Server running on another machine (not localhost). We are getting the following error:

Couchbase.N1QL.QueryClient:Information: Failed query cid1::3: http://127.0.0.1:8093/query

So it is trying to find the queryClient locally. How do we tell it that it is running on a different machine? We can get documents fine, but obviously cannot query them.

AppSetting.json:

{
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Debug",
      "Couchbase": "Debug"
    }
  },
  "Couchbase": {
    "Servers": ["http://192.168.30.199:8091/"],
    "Buckets": [
      {
        "Name": "bucket",
        "Password": "password"
      },
    ]
  }
}

Config:

public void ConfigureServices(IServiceCollection services)
{
    //Register CouchBase with configuration Section Service
    services
    .AddCouchbase(Configuration.GetSection("Couchbase"))
    .AddCouchbaseBucket<IMyBucketProvider>("bucket")
    // Add framework services.
    .AddMvc();
}

That’s a known issue as covered in the release notes. There is a workaround which involves setting up your single-node-cluster slightly differently or you can downgrade. Should be fixed in the next maintenance release.

Hi,

I am having the same issue. I am running single node CouchBase 5 in a Linux Docker container.
I have updated the hostname of the container to the IP of the Linux VM.
Still no luck.
I am using CouchNetClient 2.4.7 on ASP.Net Core 2 preview 2.

Did I change the hostname in the correct place? Or were you referring to the Linux VM it is running ?

Thanks,
