Trouble with renewing a Let's Encrypt cert

Configuration
1

I’m using Nginx Proxy Manager and DuckDNS on my HA setup. Recently, I was unable to login using myurl.duckdns.com, I could only get in using my Nabu Casa link. When trying to login I get an error that my SSL cert expired 02/10/22. But, when restarting DuckDNS or Nginx Proxy Manager they all say that my SSL cert is good until 04/12/22.

 + Valid till Apr 12 14:12:52 2022 GMT (Longer than 30 days). Skipping renew!

Here is my DuckDNS config

lets_encrypt:
  accept_terms: true
  certfile: fullchain.pem
  keyfile: privkey.pem
  algo: secp384r1
token: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
domains:
  - myurl.duckdns.org
  - myurl2.duckdns.org
aliases: []
seconds: 300

I have two URLs because one points to my HA server and the other to my Blue Iris server.

Any idea how to correct this?

I stumbled upon the solution if anyone else has this issue. The SSL cert renewed but Nginx Proxy didn’t pick it up. I went into the Nginx proxy webUI, added a new SSL cert, which pulled the renewal through, then deleted the old cert.
