Check multiple domains for LetsEncrypt CAA Rechecking Bug on Nginx servers
View Check nginx domains for CAA Rechecking bug.md

On 29th February 2020, LetsEncrypt found a bug "CAA rechecking". https://community.letsencrypt.org/t/revoking-certain-certificates-on-march-4/114864

This script has been made to help admins to check multiple domains on their Nginx web servers.

All my domains where fine, so I didn't bother to automate renewals. However, it can be added in the script.

Quick Usage:

wget -O - https://gist.githubusercontent.com/sashareds/98095b8b7b322c8283dc7afbec658690/raw/019fcc59f92ada15ae6eebd80d544db6828caeb0/checkforcaa.sh | bash
