Dear All!

Error as same figure:

i did setup let’t Encrypt. But site is using self-signed.
I wanted to remove certify Type self-signed!
I create let’s encrypt error:
Requesting a certificate for danit123.com, www.danit123.com from Let’s Encrypt …
… request failed : Web-based validation failed : The native Let’s Encrypt client was used previously on this system, and must be used for all future certificate requests DNS-based validation failed : The native Let’s Encrypt client was used previously on this system, and must be used for all future certificate requests
Thanks!

Hi,

This error message means you will need to use the native LE client(Clients installed from your system. not self-compiled)

That's all i know.

Thank you.

Are you using some kind of control panel to try to obtain the cert? Because this message suggests this is the case.

You are serving a self-signed cert, along with the Let's Encrypt intermediate cert, but that isn't what's causing your problems. Your problems seem to stem from having previously used certbot to get a cert (there was a Let's Encrypt issued for your domain on 30 Aug 17), and you're now trying to use a different tool. The stuff left by certbot is confusing the tool you're trying to use now. The solution would be to either use certbot to renew the cert (or, better, extend it--the last cert you issued only covers danit123.com, not www.danit123.com), or to remove everything it put on your system (probably everything in /etc/letsencrypt/) and try again from the control panel.
