As of today, I cannot connect anymore to a local Windows machine using Jump Desktop. This has worked before. The error I'm getting is "Connection Error: there was an error connecting to the computer. Error code 2.50 (0x32). I'm connecting using IP Address.

- The standard MacOS application, Windows App (formerly known an Remote Desktop) can still connect

- Telnet works (the the standard RDP port)

I tried all of the following things:

- delete the connection an creating a new one. Even without filling in any credentials, this error dialog appears (which makes me think it's got nothing to do with the account)

- reboot both machines.

- change the IP address of the Windows machine.

- reinstall Jump Desktop.

- disable NLA authentication on the Windows machine.

- change settings in Computer Configuration → Administrative Templates → Windows Components → Remote Desktop Services → Remote Desktop Session Host → Security

- check Windows event logs (found nothing relevant)

I'm out of ideas.

  I'm now using Fluid, which requires installing Jump Desktop on the Windows machine. This only works because I have the necessary rights on the Windows machine, but there are off course situations where this wouldn't be possible.
