site is not secure

[thetechnodino]

Version 116.0.5845.140. Installed from Flatpack
OS: Fedora 38
Using Proton VPN

Every attempt to connect to a site gives the error:
Examples include: duckduckgo and Google.

site can't be reached. Server IP address cannot be found.

Further investigating, clicking on the information button (I inside a circle) shows the following error:

Your connection to this site is not secure.

This error inspite of using: https.

Any help greatly appreciated.

Thanks

Seems like a network issue on your side or with your VPN. Also, please report flatpak issues in https://github.com/flathub/com.github.Eloston.UngoogledChromium.
