Unable to locate node
I have a single node that I'm trying to access using .net drivers and I'm getting the error "Unable to locate node". The weird thing is that if I create a Bucket of type "Memcached" I'm able to connect, but if the bucket type I create is Couchbase, I get the error. I tried numerous options and all failed. The fact that I can connect when the bucket type is Memcached, rules out all the firewall / Ip issues. The Couchbase bucket I'm connecting to is on Standard Port with no password.
The config in the .net program is:
<configSections>
<section name="couchbase" type="Couchbase.Configuration.CouchbaseClientSection, Couchbase"/>
</configSections>
<couchbase>
<servers bucket="atest">
<add uri="http://192.168.4.218:8091/pools"/>
</servers>
</couchbase>
<appSettings>
<add key="ConnectionString" value="blabla" />
</appSettings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
</configuration>
then the code is:
_instance = New CouchbaseClient()
Dim res As IStoreOperationResult = _instance.ExecuteStore(StoreMode.Add, id, dataToAdd)
Can u point me to what I'm doing wrong?
http://192.168.4.218:8091/pools opens up successfully from remote machine (from web browser) .
Telnet works, and I created a new Couchbase Bucket with port 11220 and I did establish a telnet connection and verified that commands like stats and set are working, but the .net client is still returning the same error when setting the uri config value to
Again, this issues is only for teh Couchbase type buckets, otherwise it works well from within the .net library for MemcacheD buckets.
Installed the NLog thingy. The major error that I can see from the log is "Failed to initialize the pool.". I have followed the instructions at:

Your code and config look fine. The "Unable to locate node" error generally means that the client can't get to port 11211 or possibly 8091. From the server running the app code, are you able to connect to http://192.168.4.218:8091/pools? You might want to try logging - http://www.couchbase.com/docs/couchbase-sdk-net-1.2/couchbase-sdk-net-lo.... Also, Telnet is a good first step towards diagnosing port problems - http://www.couchbase.com/docs/couchbase-devguide-2.0/cb-basic-telnet-ops....
