@Xtr, I’m sorry that the Nginx plugin is currently not working. We do have a plugin for Nginx which has been working in the past, but currently, as you saw, it’s not quite ready to be used on live systems.
Hopefully the Nginx plugin will be updated and available in good working order soon, since we know that lots of people would like to use it. Anyone reading this with Python development experience is welcome to contribute to the project.
As you saw, it is possible to obtain certificates in another way and then configure them in Nginx, but we would certainly like to make the experience much more automatic and seamless. I’m glad you were able to get things working properly on your system, and thanks for helping us test the service.
One practical issue is that, without more complete integration, automated renewals won’t happen when your certificate expires. So bear in mind that you’ll need to get a new certificate when this one expires, presumably currently 90 days from now.
