I’m using version 0.5.0 and needed to use the standalone installation as my ISP blocks port 80. I ran the following command:
sudo ./letsencrypt-auto --authenticator standalone --installer apache
The script ran perfectly and installed certificates to:
After restarting Apache2, no browser will accept the https page.
"This site can’t be reached
business2.business refused to connect.
"This page can’t be displayed
Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://my.domain again. If this error persists, contact your site administrator."
(TLS 1, 1.1 and 1.2 are all turned on already)
Firefox gives a different error message again about the “The website does not supply ownership information” and “The website does not support encryption for the page you are viewing”
Looking at the Apache2 configuration in Webmin, it appears to be set up OK by the standalone function:
SSL protocols TLSv1 TLSv1.1 TLSv1.2
Certificate/private key file
Private key file
Is there some other task that needs to be done so that Apache2 serves the pem files to the web clients after running the standalone installer?
