LetsEncrypt Wildcard Cert?

[plonka2000 (Kareem)]

I’m using LetsEncrypt and Nginx via the certbot addon on hass.io

I’m wondering if anyone has gotten the LetsEncrypt wildcard support to work as yet, and if there are any details I can find?

LetsEncrypt added this functionality during 13th March 2018.

Is it as easy as just changing my config to request and use a “*.mydomain.com” Windcard cert?

Using it via haproxy in front of home assistant and no issues. I use the ACME project to automate the renewals and such.

Thanks, is the process identical to any other cert request?

In the url field I used to use home.mydomain.com and now I use *.mydomain.com and it works… Just make sure to change the issuing server to the V2 which does wildcards.

Thanks, this is exactly what I was hoping for.

I’ll check the hass.io add-on documentation to see if there is any reference to this.

For details, I’m using these add-ons:
