Embedded RDP sessions are not working on MacOS

Hey,

I've been trying to establish multiple embedded RDP sessions with the latest Remote Desktop Manager for MacOS (2026.1.8.6), but none of them worked.

I tried to establish "plain" RDP sessions (direct connection to the target machine), but it didn't work.
I also tried to establish CyberArk's SIA-RDP connections (with RD Gateway), but it didn't work either.
The message I keep getting is "unable to connect to host - CONNECT_FAILED (0x00020006)". I also tried to change the hostname to the public IP, but it didn't work as well.

The thing is - I tried all of those sessions with an external RDP client (Windows App triggered via Remote Desktop Manager), and all of them worked.

I asked a team member to try on their machine and they got the same issue.

The way I configured my RDP sessions was by importing RDP files, which, again, worked well on Windows App.

My setup:

• MacOS Tahoe (26.3.1)
• Latest Remote Desktop Manager version (2026.1.8.6)
• Palo Alto Networks VPN
