Debian 12 discover error message on update

When I go to Update in the software Discover in Debian 12, I get the following error message: E: https://download.sublimetext.com apt/stable/ InRelease is not (yet) available (Could not connect to 160.86.242.23:8080 (160.86.242.23), connection timed out) E: http://security.debian.org/debian-security bookworm-security InRelease is not (yet) available (Could not connect to 160.86.242.23:8080 (160.86.242.23), connection timed out) E: https://deb.nodesource.com/node_22.x nodistro InRelease is not (yet) available (Could not connect to 160.86.242.23:8080 (160.86.242.23), connection timed out) E: https://linux.teamviewer.com/deb stable InRelease is not (yet) available (Could not connect to 160.86.242.23:8080 (160.86.242.23), connection timed out) E: http://debian.otenet.gr/debian bookworm InRelease is not (yet) available (Could not connect to 160.86.242.23:8080 (160.86.242.23), connection timed out) E: https://cli.github.com/packages stable InRelease is not (yet) available (Could not connect to 160.86.242.23:8080 (160.86.242.23), connection timed out) E: http://debian.otenet.gr/debian bookworm-updates InRelease is not (yet) available (Unable to connect to 160.86.242.23:8080:) Can someone tell me what is happening and how I can fix it? I don't have similar behavior when I do: sudo apt update && sudo apt upgrade or flatpak update. It is only through Discover and I need Discover because I use KDE and have addons. I would also appreciate if someone new how I can update KDE addons from the command line.
