Connected to wifi but no Internet v2

Dear community,
unfortunately i ran into the exact same issue as this guy:

Connected with wifi but no Internet after F37 upgrade

Hi, I have a problem with my Fedora 37 Laptop. I can’t go in the internet. On the network page is shown that i’m connected but then at the activity bar there is an asking sign over the wifi simbol. The same problem also with the Ethernet. I had this problem after the F37 upgrade, and there is no way to go in the internet. I tryed multiple kernels but that changed nothing [eb32b825a76bfbef9b0d8bc17fb7b84d897ceb4d.jpeg]

(solution: perform an update) → My Problem: I can not do it the same way he did (see below)

After some reboots my internet connection suddenly stopped working on my IdeaPad 5 Pro 14ACN6 / Fedora 38 (Budgie). It is not a hardware problem. Running a live USB with F38 works perfectly fine. So do other computers in the same network. I tried different Wifi networks, all show the ‘connected to Wifi’ symbol without any further notes/hints. In Software Manager → Updates is listed, that it is/was/wanted to downloading/download a system update (looks like it did not finish (or even start (?), maybe i interrupted).

Regarding the mentioned discussion (solution) above: I do not have a VPN installed that is able to circumvent the issue. I have Proton VPN installed, even with alternative routing activated it does not work. However running Tor browser works perfectly fine. It does not help me with the `update is the solution’ problem, when i can not perform an update due to missing (working) internet connection. Other solutions mentioned in the article above I already tried without success.

Does anyone of you guys have a solution for this problem?

Thank you in advance guys, lets hope my english worked to describe the Issue :))

Sounds like a DNS related issue, try using a public DNS.
If the issue persists, collect the diagnostics:

resolvectl --no-pager status; resolvectl query example.org
tracepath -4nm10 example.org; tracepath -6nm10 example.org

I did change the DNS and tried differend puplic DNS:

Unfortunately the first line of commands did not work, the command is unknown…
Second line had these results:

(Internet is still not working)

sudo tee /etc/resolv.conf << EOF > /dev/null
nameserver 1.1.1.1
nameserver 8.8.8.8
EOF
sudo dnf -y install systemd systemd-resolved
sudo dnf -y reinstall systemd systemd-resolved
sudo systemctl enable systemd-resolved.service
sudo systemctl restart systemd-resolved.service
sudo ln -f -r -s /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

If there’s an error, disable IPv6 in the connection settings and try again.
