Connection is pretty slow in the local network

Couchbase Server
1

Hi,

I am not sure if this is right place to ask the question.

I have a couchbase installed on the ubuntu system. Although this couchbase can be accessible, but the first connection is quite slow.

I have to setup the connection time as 20 seconds, and the default one 5 seconds is not working.

I have asked my IT support and they proved that there was not connection problem between my machine and local couchbase hoster. The ping and telnet show that the connection is quite healthy.

Can somebody pitch some help on this topic?

My environment is listed in below
JAVA JDK 1.7
JAVA SDK 2.1
Couchbase 4.1 on ubuntu

Many thanks.

Hi,

Can you please check if there’s any firewall settings on the node that prevents CB from communicating to the client? Here are all the network ports that CB needs to communicate.
