Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
The operating system my web server runs on is (include version): Debian GNU/Linux 9 (Jessie)
My hosting provider, if applicable, is:
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
Description:
In my apache configuration I redirect the / of http://slat.org to https://slat.org. When renew certification it gave me error like in the pastebin.
Thank you for your suggestion. The basic concept is to make the visit of acme-challenge keep in http instead of redirecting to https. (For this time I changed the config to remove the Redirect temporarily. It then renewed my certification successfully.) I’ll try your setting suggestion when having the same issue at next renewal
I don’t know how many people facing the same problem. If anyone have the same problem please feedback here and maybe it can be put in the FAQ. (Or it can be solved?)
