NoMastheadMatchesURL on Gather Status Page

I have multiple relays that are showing the same gather errors in GatherState.xml. They show the following:

Url: http://sync.bigfix.com/cgi-bin/bfgather/ibmlicensereporting
Error Message: 50: class NoMastheadMatchesURL

I’ve searched around and can’t seem to find much info on this error. Can anyone offer some insight on it? Thanks!

This error essentially means that a child Relay or Client requested a site that is not currently subscribed in the environment (or at least it’s masthead is not in the Relay’s actionsite). Generally, if the site in question is not subscribed in the Console, this error can safely be ignored (we are exploring methods to better handle these sorts of errors moving forward).

Isn’t the source of the issue that an Endpoint is requesting the missing site content from the Relay, and the Relay is unable to retrieve it from the server?
