C# trying to access couchbase via sdk error

I am getting this error while trying the example from the below page:

https://developer.couchbase.com/documentation/server/current/sdk/dotnet/start-using-sdk.html

“The node 127.0.0.1:11210 that the key was mapped to is either down or unreachable. The SDK will continue to try to connect every 1000ms. Until it can connect every operation routed to it will fail with this exception.”}
The node 127.0.0.1:11210 that the key was mapped to is either down or unreachable. The SDK will continue to try to connect every 1000ms. Until it can connect every operation routed to it will fail with this exception."
Couchbase.IO.ResponseStatus.NodeUnavailable

using visual studio 2017
and 2.5.8 of the couchbase api

I can access the node via the couchbase console and I am using localhost as the system name
http://localhost:8091

the connection succeeds but the upsert does not (fails with the above error) and suggestions welcomed

thanks

Hi @dougc,

In the future, you might want to post C# questions to the .NET SDK Forum: https://forums.couchbase.com/c/net-sdk

Would you mind posting a sample of your configuration and code?
