Does anyone have a working LetsEncrypt addon config

As per title please.

I have no idea how to setup a config for this. I usually get a reminder from LetsEncrypt to remind me that my cert is going to expire, so i just use certbot command line to request a renew, but I have to turn off my webserver so that LetsEncrypt can challenge on port 80.

How might this get crafted in the addon config please?
