Fedora suddenly won't connect (lemmy.ml)

Hey I'm hoping someone here can lead me to help.

I updated fedora yesterday and all was working, shut down, still working on boot today, but I had to reboot for an unrelated issue (touchpad multi-touch wasn't working, it happens, reboots fix it) and now I can't connect to the internet.

Except I am connected to my router just fine, and my wifi works on my other devices, but my laptop refuses to connect to anything outside despite assuring me it is connected. Still can't connect to my VPN, tor, websites (browser or ping), torrents, or slsk. Whether or not my vpn is disabled, no matter, no "working" connection, despite insisting it is connected.

Any help is much appreciated.

This post is quite old, so it's probably already to late but I can try to help. I'm not sure what network manager Fedora uses, but you could try to narrow the issue down. Here are the steps I would take if I were you:

Check system logs with journalctl -e and see if there's anything strange there
Confirm that I have a local IP address with ip addr (next to your network device name, should be something like wlpxxx for Wi-Fi)
Try to ping a popular server, e.g. ping 8.8.8.8 for Google DNS
Try to check whether DNS works with dig google.com
Check what route my packets take on the way to the server with tracepath 8.8.8.8
If any of these are out of the ordinary, I'd try to google the error and see what else can be done

If you have any questions, feel free to ask. I'd be happy to help

Replying from my other acct, but it seems the issue was with the VPN (mostly). Possibly two issues at once, as it wasn't working without the VPN for a spell too, but then it came around in the end on it's own, but the VPN problem persisted, and then resolved itself in time as well. No clue why, and no clue why my ports are still listed "open" though the VPN supposedly removed my ability to do so. Life is full of mysteries.
