Describe the bug
Tried to add a certificate via DNS Challenge for Cloudflare domain. After starting the process, a timeout error appears. If the propagation seconds are set, an error is given hinting at conflicting dependencies with the certbot-dns-cloudflare pip package.

Nginx Proxy Manager Version
v2.9.15

To Reproduce
Steps to reproduce the behavior:

1. Go to the tab "SSL Certificates"
2. Click on "Add SSL Certificate"
3. Enter the domains "*.example.com, example.com"
4. Select "Use DNS Challenge", Cloudflare, and set API Key
5. Set Propagation Seconds (450 Seconds) (Optional)

Expected behavior
A SSL Wildcard Certificate is created.

I have the same problem.

have you created an api key with dns edit for all zones or a single zone?

have you tried making a new key?

Related to #1769 which is an issue we've been tracking now for a while.

Yes, created a new key, edit for all zones. Tested the key with the curl command given by cloudflare.

Just discovered this after much investigation. Related to #1769

I will test the recommended fixes and report back.

As suggested in the issue linked by @jiriteach I changed my nginx proxy manager version from latest to the previous version 2.9.14 and it worked fine.

version: '3'
services:
  app:
    image: 'jc21/nginx-proxy-manager:2.9.14'
    restart: unless-stopped
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt

Let's Encrypt certificates in combination with Cloudflare DNS are being generated now.
Thank You

I was having the same problem. I tired about six months ago and received the same error. I had some time this weekend to try to get it up and going. Again, I received the same error. I realized what it was. When you paste in your API key, if you look very careful, prior to the equal sign "=" there is a space. Remove the space and you should be good to go. I zoomed in on @cryd-s image, and it appears to have the same space. Hope that helps :)
