PSA: LetsEncrypt ending expiration notification emails
Since its inception, Let’s Encrypt has been sending expiration notification emails to subscribers that have provided an email address to us. We will be ending this service on June 4, 2025. The decision to end this service is the result of the following factors: Over the past 10 years more and ...
I think it's a good idea, everyone should be automating this anyway.
Those emails have warned me something was pooched in advance many times. I do find them useful.
Sad to see them go, but nice they mention an alternative.
I’ve mainly gotten false positives, myself. When I’ve added another subdomain or something and the certificate gets set up differently, so then you get 2-3 emails saying domain X will expire, but if you connect to the url you see it has 80+ days left. Setting up your own monitoring solution is probably long overdue for myself, and it’s nice I’m getting forced to do it, in a way
I did setup UptimeKuma for notifications on this. let's see if it works out when the expiry arrives in a month
I think I'll need to add notifications for my uptime kuma as well now. So far I've used it mostly for historical data but without the mails, I would like to get a notice
UptimeKuma looks nice. Simple, but it does what it is supposed to.
Just needs an API and an export/import feature.
I think it's a good idea, everyone should be automating this anyway.
This is still not possible in all scenarios. For example, wildcard certificates for DNS providers with no API support.
I manage all my certs using Cert Warden which has a dashboard that displays the expiry date. It does lack alerting, so I use Uptime-kuma to monitor the expiry dates of the certs. So not a big loss for me.
If you're using Prometheus, Blackbox exporter checks cert expiration as well
PSA: If you use Cloudflare to proxy, you can get a free decade long certificate and not worry about it for awhile.
Oh, look: the NSA dangling a carrot on a line.
Hey, if you wanna put your home server out there so the first person who gets pissy at you can DDoS you off the net until your ISP decides to cancel your service, that's a perfectly acceptable decision to make for yourself.
Mine just auto renews anyway
I think thats the case for most of us. But for some like myself, it does mean I have to do the monitoring myself now. I can't complain it was a free service. But it did warn me about a renewal problem before the cert expired, so it was a useful service for me.
I have my home assistant check and also my nagios, better safe then sorry
Dietpi has an automatic letsencrypt recert service which could probably be ported since its just a whiptail script
Just use certbot and cron.
