yeah - thanks for your rather unsympathetic responses. I should be grateful if you would bear in mind that I am simply an end user and I know nothing about this subject. Whatever you might claim, the first I heard about your service was when I started receiving emails saying that my certificate was running out. I never applied for one - I'm guessing that it is a deal you guys must have with Synology. But I now find that I can't remotely access my Synology.
If I don't fill in your form It's because I am not an IT specialist, just an historian faced with an issue I don't understand. Two IT companies I have approached with this issue both declined to get involved because they couldn't understand it. One of them was the one that set up the Synology in the first place. So something is not self-evident, even for IT specialists.
Here's the text of the email I get.
Your certificate (or certificates) for the names listed below will expire in 20 days (on 2023-06-17). Please make sure to renew your certificate before then, or visitors to your web site will encounter errors.
We recommend renewing certificates automatically when they have a third of their total lifetime left. For Let's Encrypt's current 90-day certificates, that means renewing 30 days before expiration. See Integration Guide - Let's Encrypt for details.
For details about when we send these emails, please visit: Expiration Emails - Let's Encrypt In particular, note that this reminder email is still sent if you've obtained a slightly different certificate by adding or removing names. If you've replaced this certificate with a newer one that covers more or fewer names than the list above, you may be able to ignore this message.
For any questions or support, please visit: https://community.letsencrypt.org/ Unfortunately, we can't provide support by email.
