I have setup SSL certificates with letsencrypt and ISPConfig 3 (on a cheap hosting service).
Installed letsencrypt on a Ubuntu desktop:
git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
./letsencrypt-auto
Created the certificates:
./letsencrypt-auto certonly --manual
and filled out the fields in the SSL tab domain-settings in the ISPConfig hosting control panel.
Then I copied:
- contents of
/etc/letsencrypt/live/domain/privkey.pem
to theSSL Key
field - contents of
/etc/letsencrypt/live/domain/cert.pem
to theSSL Certificate
field
And saved the certificates.
Now Opera, Chromium and Explorer all give a secure connection, but Firefox claims the connection is not secure.
How to fix that?
