Hello, 

has anybody used the letsencrypt for Odoo 9?
It's located in https://github.com/OCA/server-tools/tree/9.0/letsencrypt

I've installed it but after that I do not know what to do. I was trying to install letsencrypt without this module first, straight in the server (ubuntu), but I was stopped because the Acme challenge didn't go through (couldn't access the acme link since Odoo is showing the 404 page there instead).

After the install of letsencrypt, it is said "After the first run, you'll find a file called "domain.crt" in $datadir/letsencrypt". I can't find that kind of file or folder at all.

Any more specific guides for this?

Have a look here:

https://github.com/OCA/server-tools/tree/8.0/letsencrypt

or here:

\https://goclouder.net

Goclouder is a Docker management tool and does support the management of certs.

Im looking also to a solution for using nginx and letsencrypt on a Ubuntu server.

I can create the certificates in the standalone mode but to do this I have to stop the werbserver.

For auto-renewal I would have to run the webroot mode. But that does not work, because I don't now how to integrate the path to the webroot and the well-known dir.

 location ~ /.well-known {
                allow all;
        }
