@ahrasis i have a single server setup with few websites I have followed the perfect server setup on my debain 9.13 (stretch) earlier and used your script to setup Letsencrypt. i had a many months of trouble free operation and my Vultr VPS server runs without any problem. This December my server failed to renew itself through the cron script. I understood that your script is deprecated and followed your advice to remove the script and subsequent recommended changes. Somewhere in between i got lost and my server is in a state of limbo. i will try to troubleshoot with the faq @till has provided. honestly, i am skeptical because of the state of limbo I mentioned earlier. can you please help with step by step check list to find out what is missing and its resolution. Feeling lost and helpless edit: i will do the steps mentioned int he FAQ and let you all know when i get struck up.
