Is duck DNS really down or is it just for me? Downdetector shows its up. I can't access from firefox, can't ping it or curl it.

My vailtwarden server uses duck DNS to issue a certificate and use https but recently I've been having trouble using since duckdns is almost always down.

Edit: turns out my pihole was blocking it. I have no idea why but some of my adlists added duckdns in the blocklist.

No clue. Don't use it myself. I am able to access the website so I would assume the rest is up and working.

Your ISP may be blocking access (many ISP's do not allow hosting things on home connections so check your TOS.) Why they would block access to the website I have no clue but they could see allowing it as allowing people to host a service.

Disconnect your phone from wifi and see if you can access DuckDNS. You can also do some troubleshooting and testing https://www.golinuxcloud.com/how-to-check-if-isp-is-blocking-website/

Also depending on your router if you can setup DNS over TLS or DNS over HTTPS and use two different DNS providers not controlled by your ISP.

If you're using an ISP provided Modem/Router you should probably consider setting up a proper firewall router and get just a modem or put the modem/router in bridge mode so you don't double NAT.
