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.
