Not working on Windows 7 without DNSCrypt Proxy

[anjari]

I'm using PowerTunnel v2.5.2 in Windows 7 and Windows 10.

To make it work in Windows 10, I only need to change the DNS Profile setting from "Custom" to "Cloudflare (DOH)". I use the default value for other settings.

But in Windows 7, the PowerTunnel doesn't work at all (I still can't access the blocked websites). I have tried tweaking the DNS plugin settings and some of main options, but nothing works.

I can only make it work in Windows 7 by running DNSCrypt Proxy first (I use this GUI app with Cisco OpenDNS provider), and then I starts the PowerTunnel server (the plugin's DNS Profile setting doesn't matter in this case, I can set it to the default "Custom" and it will still work fine).

There is no error message at all in the console log:

Are you connecting to the same network from these two machines?
Do you have the same DNS configuration (or lack thereof) in your browsers?

Yes, both connect to same network, and I use same DNS configuration in the browser (I had tried tweaking the secure DNS setting in browser, but nothing works). I have two Windows 7 PC, and both have same issue.
