All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/tellmebye.com/fullchain.pem (failure)

My web server is (include version): apache2 2.4.18-2ubuntu3.13
The operating system my web server runs on is (include version): Ubuntu 16.04.3 LTS

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no, i’m using ssh

I’m not sure why that error is happening, but version 0.4.1 is really old. (In fact, the project renamed from letsencrypt to Certbot soon after 0.4.1 was released!) It even uses Let’s Encrypt’s old ACMEv1 API, which is being phased out.
