What is the LAN server synchronized to?
Does the LAN server have a refclock too?
Likely there is no intersection / overlap of the two sources.
prefer the ref clock?
increase tos mindist?

Once you have the refclock dialed in,
you can try setting the LAN server to noselect,
run for a day or so,
and see how far it strays relative to the refclock {probably within 20-25ms},
increase the mindist, and remove the noselect for the LAN server
