Request new Let's encrypt certificat with Debian Jessie

Hello i have an error message when i would request a new Let's Encrypt certificate

Error: urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Error creating new authz :: Validations for new domains are disabled in the V1 API (https://community.letsencrypt.org/t/end-of-life-plan-for-acmev1/88430)

Howdy -- thanks for contacting us!

Unfortunately, Debian Jessie has reached it's end of life, it's no longer supported by Debian or Virtualmin... that means you may indeed run into problems while using it.

We'd highly recommend upgrading to a supported distribution version.

Out of curiosity though, what is the output of these commands:

dpkg -l 'webmin-virtual-server'
certbot --version
