My domain is: sise-it.com
I ran this command: ./letsencrypt-auto; after that i selected my subdomain office.sise-it.com
I already do have the cert for the main Domain.
It produced this output: “Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA.”
My web server is (include version): Apache2
The operating system my web server runs on is (include version): Ubuntu 16.04 LTS
My hosting provider, if applicable, is: I have my own server at home and im using Dyndns A-Record with namecheap
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no
My Question now is: Can i obtain a cert for my subdomain with any workaround? Or do i just have to wait for any bugfix? Is this a Problem of my Internet Provider or my Domain Provider, or even both?
Or is it even my fault? In the past i never had problems with this…
