It say: Congratulation after use letsencrypt to register ssl, but I still cannot use https


Hi Letsencrypt,

My domain is:

I ran this command: ./letsencrypt-auto then work step by step

Finally, It say: Congratulation… but I still cannot use:

My operating system is (include version): CentOs 7

My web server is (include version): Apache 2.4.6 (CentOs)

It’s my hosting: IP:

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no, I use ssh command line and installed letsencrypt through terminal.

Best Regards,


Have you got a firewall blocking access to port 443 ?

Is the server listening on port 443 ( netstat -tulpn | grep 443 ) ?


Yes, I checked it:
I think my problem is same: Failed to connect to x.x.x.x:443 for TLS-SNI-01 not able to setup certificate


Note: you’ve got multiple certificates issued today. Not every certificate has the “www” host included. If you also need a certificate for “” you’ll need to use this certificate: (good luck finding the right one on your server ;))

No it isn’t: in that topic the problem is getting your domain validated, even before issuing a certificate. You already have multiple certificates issued for your domain (see above).

Your problem is your webserver configuration.


Thank you very much.
Can you tell me how can I download this certificate and covert it to pem file.
I have not much experience. Thank in advanced.


It should be already on your server. Take a look around in /etc/letsencrypt/ :slight_smile:
