Tickets



The first of these tickets seems to have a different error

("could not connect to session bus failed to connect to socket /tmp/dbus-2us4B9PQ5X: Connection refused")

from the other two

("We couldn't connect to the remote PC. Make sure the PC is turned on and connected to the network, and that remote access is enabled. Error code: 0x204")

The latter two also seem to be both running the same OS (11.2.3)

There's a suggestion here: https://docs.microsoft.com/en-us/answers/questions/163352/after-big-sur-was-loaded-on-mac-book-pro-now-the-m.html that the 0x204 problem can be fixed by turning off hardware acceleration

(cc: That idea did NOT work for RT:107473. But connecting via the University VPN did make Remote Desktop start working again.)

timc: My Mac seemed to work fine, not sure if you wanted reports on that or not but anyway ... I tried staff.xrdp and timc.remote (vxrdppool3) and both worked fine: RDP v8.0.44 (Build 30030), MacOS Catalina v10.15.7, not using any VPN.


cc: I can connect to every single one of those addresses I listed in my mail, both without a VPN and while using OpenVPN (Informatics-EdLAN-AT). macOS 11.2.3 Big Sur, Microsoft Remote Desktop Version 10.5.2 (1863).

I can get an error 0x204 failure by dropping my VPN connection then trying to connect to my DICE desktop, which is only available inside the Informatics firewall.

I can get an error 0x104 by trying to connect to some hostname that doesn't exist (blibbyblobby.inf.ed.ac.uk in this case!)


Alastair reported at noon (30 Mar) that he could no longer reproduce the problem.

Back when he still could reproduce the problem, he could reliably avoid it, and connect a session, by connecting to the server's numeric IP address instead of to a service name or hostname.

rarmstr1: I can connect to staff.xrdp.inf.ed.ac.uk, rarmstr1.remote.inf.ed.ac.uk, archlute.inf.ed.ac.uk and mephisto.inf.ed.ac.uk with no issues. macOS Catalina 10.15.7, Microsoft Remote Desktop 10.5.2 using Informatics-EdLAN-Forum
(added by cc) ndandoul: I found a Mac lying around and I can confirm that: RDP worked for both ndandoul.remote and herakleion.inf when connected to inf-DHCP, to eduroam to OpenVPN but NOT when connected from me EE mobile network (same error as per the tickets). So I doubt it's a UK-location thing
