Nginx Proxy Manager fails to create SSL certificate when selecting Cloudflare DNS challange and providing the Cloudflare API token.

[Travel-dev159]

Nginx Proxy Manager app version: v2.12.4
Nginx Proxy Manager fails to create SSL certificate when selecting Cloudflare DNS challange and providing the Cloudflare API token.

Error message:
CommandError: ERROR: Cannot install certbot-dns-cloudflare==4.0.0 and cloudflare==4.0.* because these package versions have conflicting dependencies.

Many suggest to downgrade for example v2.12.3. This is not an option for me because the app is installed through TrueNAS catalogue and it installs the latest application. This is a fresh installation, I don't have earlier version.
Please suggest me a solution how I can get the certificate installed and working.
Thank you.

OS: TrueNAS 25.04.1 - Fangtooth

has probably something to do with python dependencies

[kooori]

Same here v2.12.4. Unable to downgrade.

I also can't login and get API Gateway error.

[aygupt1822]

I am getting same error. I am using the latest docker image : jc21/nginx-proxy-manager:2.12.4.

I downgraded to previous stable version 2.12.3 and it works. Maybe this a bug in the latest version.

No worries, the API token provided here is revoked, damn mornings..

Downgrading to 2.12.3 worked for me. I recognized there was an issue when I got 502 Bad Gateways when attempting to log in, then saw the same error spam as mentioned in the comments here. I am also using Cloudflare API keys to generate certificates.

[Travel-dev159]

Guys, I understand that downgrading to earlier version solvs the issue. On another system, it was working totally well.
This is a fresh install and I use TrueNAS catalog which installs the latest versions and I am not aware of being able to select earlier version.
What else could I do?

[StancuFlorin]

downgraded it to jc21/nginx-proxy-manager:2.12.3 and it is working fine

the issue seems to be only on the latest release 2.13.4

[ra-lukas]

Having a similar issue on AWS Route 53 when creating SSL Cert with the following error:

certbot: error: unrecognized arguments: --dns-route53-propagation-seconds 120

Feels like certbot no longer uses it, but NPM does...?
