Unable to renew LesEncrypt cert

Traefik Traefik v2
,
1

Hello all,

I've been using Traefik + Docker + LetsEncrypt fine for a few months, but now the certs are expired.
I've tried a few method to renew it but no luck.

I even spun up a new Traefik v2.2.1 container.
A few subdomains only running if I set my A record to Proxied from DNS Only in Cloudflare.
Traefik https url wouldn’t run regardless if I set it as Proxied or DNS only mode.

Cloudflare: SSL mode: Full
Registrar: NoIP
ACME challenge method: HTTP

Error:
