I have 3 similar servers, all have the same problem. I didn’t change nothing important since last certs update when everything works fine.
My domain is: apps.feramat.com
I ran this command: /usr/local/bin/certbot-auto certonly --standalone --email xxx -d apps.feramat.com --renew-by-default
It produced this output:
Detail: Invalid response from http://apps.feramat.com/.well-known/acme-challenge/TTM80RMncmzPU9_nzT3wJBezP8D0qmBmjbqdHb8jINI [2a00:1ed0:1:1800:7:2d:8c00:1]: "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN” “http://www.w3.org/TR/xhtml1/DT”
