RDM not resolving localhost

Hello Wait, this is weird: your original screenshot shows the error message in the tab, but there's no RDP hex code there. Just to confirm, based on your last message; an RDP connection to a local IP address is working, right? Kind regards,

Ok, the local IP one was false positive... the machine had been shutdown by someone. So we're back to the rest of what I posted.

RDM not resolving localhost

Hi Richard, This is most definitely looking like a "my machine" problem now - it has gotten worse as it is not connecting to local IP as though it does not have access to the network. I had looked at the local network permissions and RDM is enabled there. I closed RDM and disabled it though, restarted my Mac (overkill), then re-enabled network for RDM, and still the same. I tried 127.0.0.1, it didn't work, but as with how I started my reply, it is now not connecting to a (local) IP address. Toggling the local network access has now changed the message to Connection failed (0x00020006) , and this is trying to RDP to a local IP address. I'm at a loss as to what is going on.

RDM not resolving localhost

Hello My gut feeling is that this might relate to the Local Network Access permission for the application; although unless Apple changed something here in 27 (I didn't see it in the release notes) it shouldn't gate access to the loopback address. However it would affect DNS because if the app is denied permission here, it can't get responses from mDNSResponder. Can it be a network ordering issue? Because, localhost resolves both 127.0.0.1 and ::1, and ::1 is usually first. If the AnyDesk tunnel is only binding IPv4 that could definitely have got broken "somewhere". The simplest test is, does it work if you use 127.0.0.1 instead of localhost? In System Settings > Privacy and Security > Local Network; I guess that Remote Desktop Manager is listed and enabled? It would be worth toggling it off and on again, and relaunching the app. When you talk about broken name resolution, is it .local / short hostnames specifically or also fully qualified public names? Please, let me know if something isn't clear or you have further questions Kind regards,

Update: it looks like anything requiring name resolution is not working properly.

RDM not resolving localhost

I have a situation where I connect to customer sites using AnyDesk making use of its TCP tunnelling feature (it is tons more stable than their big name VPN). The TCP tunnelling allows mapping a local port to a remote host port, then locally I connect to localhost and a custom port number. The custom port number isn't a requirement, but I have created a register of customer servers I connect to and assigned a unique local port number so that I can connect to multiple sites at the same time, i.e., instead of mapping 3389 on the remote host to 3389 locally I map local ports in the range of 10000-11000 to 3389 for the different servers. This has all been working great until either of Mac OS 27 or the new RDM Mac version (2026.3.0.5) where now RDM is stating Unable to connect to host localhost , however a test connection to the same is working fine and the backup RDP tool (Windows app for just in case) is connecting just fine.

RDM 2026.3.0.5 ignores UI sort priority and other glitches

Hi Jesse, I only checked folders in different vaults, so you could be right that it is limited to folders only. Best regards, Jelle Hillen

RDM 2026.3.0.5 ignores UI sort priority and other glitches

Hi, Running RDM 2026.3.0.5 on macOS 15.7.9 and encountered several glitches. The sort order (from the UI section when editing a session) seems to be ignored in the navigation tree. It just sorts alphabetically. And the folder editing is basically unreadable/unusable: [image] I haven't tried all other session types but editing RDP does seem to work normally at least. Best regards, Jelle Hillen

Not every button is clickable when using Simplified Ribbon in RDM 2026.3.0.5

Hi, With the new layout (with the very large ribbon), I decided to try out the Simplified Ribbon to maximize the workspace. I did notice that buttons behind the ellipse (...) aren't always clickable. An example from the File tab, where Preferences and Exit aren't clickable (they also don't highlight when hovering over it). [image] Best regards, Jelle Hillen

This is odd. MRU is the entry that stores your "most recently used" data. It's saved in the user settings vault (not visible in the UI) and should not be listed in the Offline Sync window. I'll double-check and make the appropriate fix. For now, you can accept and hit OK. Best regards,

RDM built-in VNC (default) sends unsupported key codes

Hello Sorry about this. We do enable the QEMU pseudo-encodings if the server supports it, and that was specifically to properly support ProxMox. I was not aware that there a VNC server would support the encoding but disregard the scan codes from the key message. VNC is a little bit like the Wild West in this way, when we consider feature sets and server support. I've made a fix that we'll no longer advertise the QEMU encoding unless we know we're talking to a ProxMox host. That will be in 2026.3.1 and any subsequent 2026.2 releases (although I'm not sure if there will be any more 2026.2 releases at this time). Once again, sorry for the inconvenience. The workaround for now is to downgrade to the a version before the problematic one you identify until the fix is released, or use a 3rd party VNC client and "external" mode in RDM. Please let me know if you have further questions or comments Kind regards,
