[collectd] collectd client / server network plugin advice required

Hi, We are having trouble getting collectd client / server networking working. We think out client / server can talk to each other but for some reason the data cpu/syslog/interface data from the client isn't getting logged into our influxdb and we're not sure why.

Below is our cut down config from both client & server.

"Client_VM_A" to connect to {"Server_VM_A" > InfluxDB}


#Hostname     "the_server"
LoadPlugin network
LoadPlugin nginx
#LoadPlugin syslog   #Not sure if we need this

<Plugin network>
        Server "" "26000"   #This is out InfluxDB Server
        Listen ""

<Plugin "nginx">
  URL ""<>


#Hostname    "the_client"
#FQDNLookup   true

LoadPlugin syslog
LoadPlugin cpu
LoadPlugin interface
LoadPlugin load
LoadPlugin memory
LoadPlugin network

<Plugin network>
        Server ""


I left the nginx part in just so that I can see data is going into influxdb, and I can see the vaules via the Influx DB Admin Interface and also via Grafana.
collectd starts without error on our client and server machines and we have run the following tcpdump command to see data arriving at the server.
    tcpdump -i eth0 -p -n -s 1500 udp port 25826
    netstat -lnp | grep collectd

Our Client is running collectd 4.10.9   (Centos 6)
Our Server is running collectd 5.6.0   (Centos 7)

Any help would be appreciated.
