Connecting via protonvpn-cli and protonvpn gui leaks my ip (Ubuntu)

VPN

Today I realized protonvpn-cli and protonvpn gui apps in Ubuntu were leaking my ip address.

I don’t know for how long this has been happening. I made the tests using ipleak.net and dnsleaktest.com .

I tried resetting config to defaults and disable web-rtc in the browser but problem persists.

Then I connected using OpenVPN and no leaks and no issues.

I always knew I shouldn’t rely on a third party app for privacy but laziness always win.

Anyways this shouldn’t happen anyways. I hope they fix this soon.

Did anyone have the same issue?

Were you leaking ipv4 or ipv6? Both? I don’t think Proton supports ipv6, so you’re better off disabling it system-wide.
I know protonvpn-cli and protonvpn gui try to block ipv6 traffic by default, but conceivably it could have failed for some reason (some error you could see in the program output).

Everything looks good here on Fedora. No leaking.

Those sites use all sorts of methods to get your browser to do stuff like make DNS requests or connect to online resources outside standard requests, like using the OS handle tasks that browsers should not do by default.

I believe this is a Linux problem I have been seeking a solution for some time. To get started search protonvpn web site for Linux DNS Leak fix.

Oh my, maybe it is time to switch distros. I’ve been using pop_os a variant of ubuntu.
