I used to be able to connect to my remote desktop with my universities VPN but now I get a security problem (error 0x1807) which my uni administrator hasn't heard of. He's able to connect from other computers to my account but not from my mac... I've tried uninstalling it and re-installing it, but maybe I'm not doing this correctly...

Tried turning NLA on and off, tried turning off the Windows firewall but no help. Just started happening a couple weeks ago.

Thank you for your advice!
I tried downloading the beta version 10.8.0 (2032) and also version 10.8.4 (2111) and both gave me the same error code: 0x207 "We couldn't connect to the remote PC. This might be due to an expired password. If this keeps happening, contact your network administrator for assistance."
I tried with different accounts and had the same result. I know that those passwords are not expired and work, because I can access the computer with those credentials when I physically use it, so sadly it seems not to resolve the problem for me.
To be honest I did not really expect it to work either, because in my case I am pretty sure it has something to do with the Windows computer I am trying to remote access. But thank you again nevertheless!
But 0x207 is deferent error code, take the look on this topic: https://learn.microsoft.com/en-us/answers/questions/1344035/rdp-error-code-0x207-macos-remote-desktop-10-8-4
Interesting. Someone on that topic suggested that it might be a problem with the computer communicating with the domain, so I tried gpupdate on the computer and it failed...
I don't have the exact Windows Updates installed which he recommends to uninstall, so I'll have to figure out something else. But this seems to be a good hint.
Thanks!
Just FYI, I resolved the issue. I don't know how and why but iPv6 was active on the problematic computer. Turning it off solved everything. The computer communicates with the domain and I can remote access normally.

I have the same issue, it seems to have a relation with finding an AD logon server.
When connecting to a machine that is not in a domain it works OK.
Connections to a domain joined machine fail; In the RDP logs I see this message:
E|2023-11-29 09:27:59.9190 +01:00|:0 {c1f5e994-2b6a-4a1c-9927-6182865d0000} <0x16d2db000> RDPSECURITYFILTER(ERR): Caught a SecFilterException during handshake: The server reported error code -1073741730. ErrorCode: NoAuthenticatingAuthority
Strange thing is that it works, if you first connect to the non-joined machine and from there open a rdp session to the domain joined machine. Then it temporarily works from the mac, until the domain joined machine is rebooted.

Nice you catch the log. I think it can be helpful to someone help us. Did you find any solution or just find the main problem?

In my case, it is a domain-joined machine that has NOT YET connected by VPN. This explanation makes perfect sense. If you log in once at the physical machine, then future Remote Desktop Mac sessions work fine. I believe the issue is NLA (Network Level Authentication) which the latest Remote Desktop Mac do not let you turn off.
My workaround for now has been to use Parallels Client for Mac for the connection right after reboot because it allows you to turn off NLA. The connection works fine in this case.
I believe it is a bug or limitation in the newest RDP Mac, but I can't find any place to submit the request.
@Gustavo Saez sorry, I didn't see your repsonse earlier.
I didn't find a solution. Instead, I downloaded Version 10.8.4 (2111) from the link mentioned by @Patrycjusz Laskowski

I have the same issue, Error 0x1807 connecting to a Windows 11 from my mac with the Microsoft Remote Desktop App (Big Sour V11.7.10) What I discovered is if I establish a RDP connection from another Windows I can connect to the Windows 11 and suddenly this fix everything, after the connection magically I can establish the RDP connection with my mac. Why?? I don't know but is the only solution for me now. UPDATE:
SOLUTION:
As another post from other user at the begining of this post. I downloaded an old version of Microsoft Remote Desktop V.10.7.9 (2011) and IT WORKS NOW!!!! the problem was not in the Windows 11, it was in te Microsoft Remote Desktop Mac's APP for me. You can download it from here:

I have the same problem.
Out of the blue some weeks ago I couldn't remote connect to a specific Windows 10 computer from my Mac (using Microsoft Remote Desktop app, newest version):
"Unable to connect - We couldn't connect to the remote PC because of a security error. If this keeps happening, contact your network administrator for assistance. Error code: 0x1807"
The strange thing is that I have some more computers in that same network (Windows 10 & 11 and also a Windows Server 2016) and all of the other remote connections still work.
I tried connecting to that specific computer from another Mac and I get the same Error code. That means, it has to be some kind of problem with the computer and not with the Mac or the Remote Desktop app.
I tried all of the suggestions from the other answer from S.Sengupta but sadly without any positive results.
Another solution attempt was activating the service TermService (Remote Desktop Services) and setting it to start automatically, instead of manually. Sadly this didn't do the trick either.
Just for clarification: the computers are all in the same domain and I am using an admin account.
I did not change any settings on the computer and I can't figure out what could have changed to break the connection. Any advice is appreciated, thank you!
EDIT: I solved my issue by turning off iPv6 on the specific Windows 10 computer, which strangely was active. After turning it off the computer could communicate with the domain again and remote access worked normally.
