It looks like there is something wrong with the dns setup that you have.
Maybe check your adguard settings. It is not related to #1734 |
As i said, same config of portmaster Linux side doesn't trigger resolving delays (even with systemd-resolved involved). And if i uninstall portmaster, no delays anymore. |
For some reason Portmaster is not able to connect with your dns server and fails. You can try changing the DNS configuration to one of the default ones and see if the issue persists. Portmaster is using WFP in the kernel drive to redirect and block connections. I dont think this is related since the log from the dns query has error coming from windows. There can be many reasons why this is failing and we dont know enough for your setup to be able to point out what specifically is miss configured |
@vlabo thanks for the feedback. I should point that the errors regarding UDP in the log appears from time to time, not always. WFP drivers seems to be really unstable/malfunctioning on 24H2 : |
@nvandamme thank you for providing more details. I just tried to reproduce it whit a clean install of protmaster and I set the dns to be
As far as I know AdGuard has its own WFP drive the same as we have our own WFP driver. |
@vlabo, i've already tried by uninstalling Adguard-windows to no avail (including a full network reset, including drivers reinstall and my windows 24H2 install is fresh from November) |
We recently shipped a new feature which is still in the Beta channel. That way Postmaster dns server will not be used and all traffic will go to the system dns or whatever application is managing the dns. If you want to try it out here is how to switch |

Upon installing portmaster on Windows 11 24H2, dns queries had dramatically slowed (before: <10ms, after 2-10s) with frequent notification of failed DNS queries (Windows Firewall is active).
I am using AdGuard Home as a local DNS resolver (installed on my router).
Basic rules applied :

DNS:
The problem seems related to the windows port only: same computer but booted in arch with portmaster doesn't induce DNS latencies with the same config.
Seems related to #1734
