Searching for the message from the screenshot returns information about some services blocked by the government DPI/firewall, and this particular case must be a false positive.
To solve this kind of problem, you can utilize censorship circumvention methods like VPN, Tor, proxy, etc.
Here’s a simple workaround, assuming that your government does not block Tor:
sudo dnf install tor
sudo systemctl enable tor.service --now
sudo torsocks dnf upgrade --refresh
