(ZCM 2017U2a appliance, single primary)

I have seen from time to time the following error. I don't get it on all the devices but it does keep popping up:

Error: [2/7/18 5:26:11 PM] JoinProxySatelliteModule JoinProxySatellite.ErrorUpdateJoinProxyConf Exception While updating joinproxy_config properties.

We do not use a proxy or a satellite server. A quick Google search revealed this Micro Focus article

https://support.microfocus.com/kb/doc.php?id=7015662

that said this was fixed in 11.4 but I am running 2017U2a so it doesn't appear to be fixed. I have seen this with versions 11.4.3 as well as 2017 previously so it is not just this version of ZENworks.

What is causing this error?

Thanks,

Dan
