IP address seems to have changed. Unable to listen on 'ns_1@127.0.0.1'

Couchbase Server

I’m seeing some problems with Couchbase 1.8. Connections to the server start with C libcouchbase library fail and in the Couchbase logs I’m seeing the error:
IP address seems to have changed. Unable to listen on ‘ns_1@127.0.0.1’.
Any ideas on what might be causing this error as the IP address definitely wasn’t changed?

edit C:\Program Files\Couchbase\Server\bin\service_register.bat
like this:
set NS_BIN=%~dp0
set NS_ROOT=%NS_BIN%…
set NS_ERTS=%NS_BIN%erlang\erts-5.8.3\bin
pushd “%NS_ROOT%“
for /f “tokens=1* delims=” %%a in (‘cmd /q/c “type bin\ipaddr.out”’) do set IP_ADDR=127.0.0.1
set NS_NAME=ns_1@127.0.0.1
if not “%1”==”” set NS_NAME=%1
pushd “%NS_ROOT%”

Then double-click it, and finally restart the computer.

Thanks for the response. What does what you have described above do?

Hi,

I tried what was described (NOTE: I’m working on Linux, so I modified /opt/couchbase/bin/couchbase-server script) but it did not resolve the issue. Any other workarounds etc. that might resolve this issue?

Hi, I have same issue,

IP address seems to have changed. Unable to listen on ‘ns_1@127.0.0.1’. (POSIX error code: ‘nxdomain’)

My couchbase is running on ubuntu.

How to resolve it.
