Microsoft Remote Desktop 10 for Mac no longer connecting; error code 0x204 RRS feed

  • Question

  • Why would this application all of a sudden stop working? It connected just fine, then stopped working on both my iMac and my MacBook Pro. There have been NO recent updates to the application. I rebooted and was able to connect again to my Windows work pc for a short time, then I'm back to it not working (even after rebooting my Macs numerous times)...Help!

    Open the Mac App Store and download app.

  • Hi,

    I want to confirm with you if RDS has been deployed to provide the remote desktop connection? Or, only establish remote desktop connection from one system to another?

    Re-install the RDC app and re-create your remote desktop connection is worthy to have a try. If problem persists, please try to download RDC beta version, and confirm that if it works. You can download the beta version from below link:

  • I moved the Microsoft Remote Desktop 10 to the Trash. Then I re-installed it, but it remembered all my settings...is that okay? And, when i tried it still gave me the same error.

    Also, I use VPN Tracker which connects just fine; it's when i try connect using Microsoft Remote Desktop for Mac that I get the error. And, my pc at work is good and ready to go (and others that have access to their own pcs are not having issues).

    Yes.

    Also, please try to download the beta version of RDC and confirm that if problem still happens.

    >I use VPN Tracker which connects just fine; it's when i try connect using Microsoft Remote Desktop for Mac that I get the error.
    So, you establish VPN to the network first. Then, establish remote desktop connection to the PC which locates on the network. 

    So, you only enable Remote Desktop Connection on the remote system (pc at work) via local System -> Remote Settings?

    If possible, please try to establish remote desktop connection to your pc at work from other system, such as other available Windows client system, and confirm that if RDP function on your remote system is working. It would be helpful to identify whether it is specific source system, or specific RDC version relate.

  • I tried downloading the beta, but my Mac gave me following error:

    “Microsoft Remote Desktop Beta.app” can’t be opened because Apple cannot check it for malicious software.

    This software needs to be updated. Contact the developer for more information.

    Chrome downloaded this file today at 9:18 AM from rink.hockeyapp.net.

    Now what should i do?

    Also, I'll answer your VPN question once our IT dept tells me the answer; i'm not too savvy with remote access...

  • I just tried my MacBook Pro and it connects. So, I believe it's something with the newest Mac OS Catalina update and Remote Desktop 10.

    Below are the credentials:

    MacBook Pro (which works):

    Mac OS High Sierra v 10.13.6

    Microsoft Remote Desktop v 10.3.3

    iMac (which does NOT work):

    Mac OS Catalina v 10.15

    Microsoft Remote Desktop v 10.3.3

    Help!

  • Hi,

    >“Microsoft Remote Desktop Beta.app” can’t be opened because Apple cannot check it for malicious software.
    It is a new function on mac OS. Just right-click the application in question and choose “Open”. Then, click the “Open” button at the next dialog warning to launch the app anyway.

    Then, confirm that if problem happens on beta version.
