I got internet issues after installing Zen | Linux | gnome

[BANZOM]

I'm on Debian 12, Gnome.
I installed Zen tomorrow.

After running it, all of my Brave tabs got an internet error. I refreshed them and then they loaded, but very slowly.

When I started my laptop today and opened the browser, it showed a connection lost (some kind of proxy error).
Then I started the Zen app and some working started...
And some websites are behaving abnormally, like WhatsApp (web.whatsapp.com), which keeps on looping on logging in.
Replit cannot get connected to my repls. I did reboot, but nothing works.

I removed the Zen app and its certificates from .local/../../../zen, but no success is there.

Help me in getting working internet.

Use these instructions to navigate to the network proxy settings and set it to "Disabled". Should do the job.

Thank you for providing this article.

Update: I noticed that when I tried to uninstall the CA button by tapping on it, it was not deleted. After referring to the issue section, I found that you advised to operate Zen with the command below.

PATH=$PATH:/usr/sbin ./Zen

Then the button works and I removed the Zen app. Since then, the internet is working fine.

Hope you'll tackle all these bugs/configurations soon.

This project has huge potential.
