Hi Geoff,

A warm welcome to the forums.

Just to be clear of where we are starting from - has this ever worked? Might you be a new user who has not yet gone fully live?

There is a known intermittent error where DNS lookups fail which might give the error you report ... but there are other scenarios which might give the same error.
