Getting certificate errors on webview browsers, while standalone browsers work flawless

Hi,

I'm getting an error message:
"Certificate authority is not trusted." while using webview browsers.

Screenshot_20240624-185444778

On "standalone" browsers like Mull or Cromite I don't have this error.

Specs:
Android 10
Free Browser v2.8
Mulch Webview v126.0.6478.110
AdAway (root) v6.1.1 with installed certificate
Root with Magisk v27.0
Modules: Systemless Hosts
                  Magisk Trust User Certs
                  Open Webview
Private DNS: unfiltered.adguard-dns.com

Anybody knows how to fix this?

Braintrain OP ,

Seems like I've found the culprit:
https://github.com/Magisk-Modules-Alt-Repo/trichromelibrary-squoosh

When I deactivate this module and try again, the error message disappears and shows up again when enabled.

Could be that your phone lacks the necessary certificate authorities. I don't think I've seen this happen on anything newer than Android 7 before, but maybe some root cert expired that I don't know about.

If you haven't already, try a reboot. The WebView server may be initialized once, and if you've just activated the cert in Magisk then you may need a reboot to activate it.

If not, I'm guessing the app explicitly does something to only use a particular system trust store.

What's the page, and what cert do you receive?
