Hi-
I am new to setting up or renewing Let's Encrypt certificates. I had assumed they'd renew automatically, but I received an email from Let's Encrypt team that we need to renew them with 18 and then 9 days left.
There have been several wildcard certs issued by LE.
[one of which will expire tomorrow]
But it is difficult to know if you are actually using it.
You also have a wildcard cert issued by Amazon: https://crt.sh/?id=3439181357
And also have one that covers the base domain and www from GoDaddy: https://crt.sh/?id=3411337344
[both of which have a year left in them]
You may need to check all your sites manually to see which certs are in use and when they are going to expire.
