We had one development agency who installed LetsEncrypt SSL certificate for us.
It seems, that certificate is about to get expired.
We don’t know how to do. And that development agency is not going to help us.
Please help us to renew the certificate, because we are non-technical.
The below is the part of the email that I received from your team:
Your certificate (or certificates) for the names listed below will expire in
9 days (on 17 May 17 04:09 +0000). Please make sure to renew
your certificate before then, or visitors to your website will encounter errors.
For any questions or support, please visit https://community.letsencrypt.org/.
Unfortunately, we can’t provide support by email.
For details about when we send these emails, please visit
https://letsencrypt.org/docs/expiration-emails/. 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.
