"Some challenges have failed"

Help
1

My domain is: homeserverdark.xyz

i'm trying to get a home server setup. I was on nginx trying to create a new certificate, and upon looking at the logs of my nginx container in portainer, the error was: some challenges have failed, I'm not exactly sure what other information i can add here besides that i can login to a root shell on my machine, and the machine is using debian
edit: i am using cloudflare

Are you using CloudFlare?

Name:      homeserverdark.xyz
Addresses: 2606:4700:3034::ac43:9deb
           2606:4700:3033::6815:5280
           104.21.82.128
           172.67.157.235

yes, im using cloudflare

Where do you want the certificate? I guess to the origin server. As far as I know, cloudflare automatically provides frontend certificates for the domains hosted there.

hold on, nevermind. i fixed the issue. i assume i made some simple error (like not typing in the api token correctly when making the cert. i was doing it late at night too) because it's all working now, so far.
