Rekordbox 6 - ProLink with XDJ on LAN - Media Collapsed or missing

Hello, I am at my wits end.  It appears something has happend with my computer that I cannot figure out why my ProLink stopped working with my XDJ 700's on my mac.

I have tried everything in every forum post and thing I could find on the internet with no results.

The XDJs link perfectly fine via the switch (and also work DIRECTLY connected to the mac), however; when you go to transfer a file (load) onto the XDJ the error "Media or File is collapsted or missing" - E-8302: Cannot Play Track(C658) shows.

I checked the database XML as well as the library file locations (nothing has changed...nothing moved ... nothing different from one day to the next)....everything is correct.  

Directly connected makes no difference if I am on my network running through switch or router; always the same result.  

I uninstalled rekordbox and whiped out all settings and databases (backed up my database just in case); and reinstalled FRESH.  Using one of the "demo" tracks" pre-packed in the software ..... SAME ISSUE!

I have disabled the firewall and allowed every level of file access, system access and network access I can find on the mac....still not working.

I am able to run everything through the network PERFECTLY fine from any other computer on my network running rekordbox EXCEPT the actual computer I USE TO DJ WITH!!!

There has to be something i haven't found that I can try.  Please help!

Running MAC OSX Catalina; Rekordbox 6.5.1
