Plugin on Mac connects to itself, wont connect to Crosspoint

[cameronetchart]

I just installed the plugin on Mac latest Calibre, but Calibre immediately connects to a "phantom" device even if my Crosspoint isn't on wifi. I can't figure out how to get my Crosspoint to connect to Calibre. I know the networking is working because if I use file transfer to connect and start web interface for transfer (no calibre), that works. Might be same issue as #5 .

The line "[22:37:46] [CrossPoint] discovered 192.168.11.9 8081" is my Calibre Mac discovering itself (11.9 is the server and then it's connecting to itself).

This may be fixed with the latest release I just put out. Please give it a test.

The original error is fixed, thanks! MacOS no longer finds a phantom device, and it discovers my actual device. (I had to move my Crosspoint to the same subnet as my server, instead of trying to use firewall rules to allow discovery from my trusted vlan to my IoT vlan, but that's not a bug IMO and reasonable for autodiscover.)

However I can't seem to be able to transfer most epubs successfully, it appears to be a filesize issue. A 371KB epub transferred, but any novel over a few MB fails. (Is Calibre doing the same optimization as the web uploader?) Here's two error logs for reference.

The same epubs transfer perfectly using the web html interface.
