my os is centos7 ,and when i run the command “./letsencrypt-auto”,
it tips : Updating letsencrypt and virtual environment dependencies…
Requesting root privileges to run with virtualenv: /root/.local/share/letsencrypt/bin/letsencrypt
No installers are available on your OS yet; try running “letsencrypt-auto certonly” to get a cert you can install manually
run as sudo
#sudo ./letsencrypt-auto — this must work
IMPORTANT NOTES: - The following errors were reported by the server: Domain: on-img.com Type: urn:acme:error:connection Detail: Failed to connect to host for DVSNI challenge Domain: www.on-img.com Type: urn:acme:error:connection Detail: Failed to connect to host for DVSNI challenge
Are the DNS records for those names pointing at the server where you ran the command? Is there another web server running on that server which was active at the time you ran the command?
