HTTPS - ACME SSL Certificates

Has anyone managed to get ACME working for SSL certificates?

I can’t find any documentation on how to do it.

In the “Web Server” section in the “Admin” menu.
Under Heading "Obtain X.509 certificate via ACME client "

ACME API URL :
I have tried

ACME Domain :
I have a ddns domain
I know my domain is reachable using HTTPS using this URL.

I always get the same response
ACME certificate : Cannot read ACME X.509 certificate.

I thought that maybe it was to do with the setting above under **Replace the X.509 certificate and private key currently used by the camera **
I have tried

  • Upload the X.509 certificate and private key
  • Upload X.509 certificate
  • Generate
    But nothing seems to work.

Has anyone gotten this working? Or can they point me to some documentation on how to get this to work?
