After updating Jumdesktop connection to Mac OS fails

I am trying to connect from iPad to Mac OS 10.15.

In the JumpDesktop Connect icon on Mac OS, i can see it is "connected" but on the remote side (the ipad in this case) I still see "Connecting..." and it stays in that state forever, never displaying the Mac OS desktop.

It was working well on previous Jumpdesktop Connect versions.

The JumpDesktop client is the current on Apple App Store.

I dont know what is failing, the client or the target.
