I installed ubuntu server VM on Azure there I installed couchbase community edition on now i need to access the couchbase using dotnet SDK but code gives me bucket not found or unreachable error. even i try configuring a public dns and gave it as ip during cluster creation but still its giving the same. even i added public dns to the host file like below 127.0.0.1 public dns The SDK log includes below 2 statements Attempted bootstrapping on endpoint "name.eastus.cloudapp.azure.com" has failed. (e80489ed) A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
