Error when doing sync from

[RichardD2]

We get the following error intermittently as nso starts (running ver5.5)

Any ideas on why?

nso-devel ncs[900]: webui 127.0.0.1 - admin [09/Feb/2021:22:06:32 +0000] "POST /restconf/data/tailf-ncs:devices/device=iosxr-r0/sync-from HTTP/1.1" 200 76 "-" "curl/7.64.0"

sounds like something that you need to report to the Cisco TAC.

What is the boolean 'webui/transport/ssl/keepalive' config parameter set to?

Hi @ttornkvi 

Looks like we don't have that setting in use. Current ncs.conf looks like this:

<webui>
    <enabled>true</enabled>
    <transport>
      <tcp>
        <enabled>true</enabled>
        <ip>0.0.0.0</ip>
        <port>8080</port>
      </tcp>
      <ssl>
        <enabled>false</enabled>
        <ip>0.0.0.0</ip>
        <port>8888</port>
        <key-file>${NCS_DIR}/var/ncs/webui/cert/host.key</key-file>
        <cert-file>${NCS_DIR}/var/ncs/webui/cert/host.cert</cert-file>
      </ssl>
    </transport>
