Certificate is not Valid


Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:
sudo certbot --apache

It produced this output:

My web server is (include version):
apchache 2.4.18

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is:
Server is running on site

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

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

I am getting the following in Chrome:

Also, my default-ssl.conf:

		ServerName kaskie-family.no-ip.org
	ServerAlias www.kaskie-family.no-ip.org

	DocumentRoot "/var/www/html"
	SSLCertificateFile /etc/letsencrypt/live/kaskie-family.no-ip.org/fullchain.pem
	SSLCertificateKeyFile /etc/letsencrypt/live/kaskie-family.no-ip.org/privkey.pem
	SSLCertificateChainFile /etc/letsencrypt/live/kaskie-family.no-ip.org/chain.pem
	Include /etc/letsencrypt/options-ssl-apache.conf



Can you try to restart the Apache?
(Just in case certbot didn’t)

Also, please run this command and share us the output. apache2ctl -S

Thank you


You’re using an old certificate issued by StartCom. However, you’ve issued two certificates from Let’s Encrypt today


But your web server isn’t using either of them. Did you do something to configure your server to use the newly-issued certificates after you issued them?


I had a hard time stopping apache! Had to run “killall” but finally got it to stop. Restarted it.

Getting this now:
This site can’t provide a secure connection
kaskie-family.no-ip.org sent an invalid response.

apache2ctl -S
AH00526: Syntax error on line 21 of /etc/apache2/sites-enabled/default-ssl.conf:
SSLCertificateFile: file '/etc/letsencrypt/live/wafka.no-ip.org/fullchain.pem' does not exist or is empty
Action '-S' failed.
The Apache error log may have more information.

The error is referring to a different VirtualHost. But to be safe, I renewed that certificate.


Congratulations! You have successfully enabled https://wafka.no-ip.org

You should test your configuration at:


  • Congratulations! Your certificate and chain have been saved at:
    Your key file has been saved at:
    Your cert will expire on 2018-08-18. To obtain a new or tweaked
    version of this certificate in the future, simply run certbot again
    with the “certonly” option. To non-interactively renew all of
    your certificates, run “certbot renew”

Can you check if those are okay? (I mean, can you try to get the Apache running… with no error?)

And them the issue might just resolved.

P.S. please check if there is any duplicate vHosts which might override the host (using startcom certs). Also, check if your domain is matching with the IP address…(just in case it doesn’t…)

Thank you


Still not working, but new error:

This site can’t provide a secure connection
kaskie-family.no-ip.org sent an invalid response.

I also got rid of the other vhost, just to test. and now running the apache2ctl -S shows this:

AH00526: Syntax error on line 27 of /etc/apache2/sites-enabled/default-ssl.conf:
SSLCertificateFile: file '/etc/letsencrypt/live/kaskie-family.no-ip.org/fullchain.pem' does not exist or is empty
Action '-S' failed.
The Apache error log may have more information.


And this is the results of the SSL test:

There are some errors that we cannot fix properly in the current version. They will be addressed in the next generation version, which is currently being developed.

No secure protocols supported - if you get this message, but you know that the site supports SSL, wait until the cache expires on its own, then try again, making sure the hostname you enter uses the "www" prefix (e.g., "www.ssllabs.com", not just "ssllabs.com").
no more data allowed for version 1 certificate - the certificate is invalid; it is declared as version 1, but uses extensions, which were introduced in version 3. Browsers might ignore this problem, but our parser is strict and refuses to proceed. We'll try to find a different parser to avoid this problem.
Failed to obtain certificate and Internal Error - errors of this type will often be reported for servers that use connection rate limits or block connections in response to unusual traffic. Problems of this type are very difficult to diagnose. If you have access to the server being tested, before reporting a problem to us, please check that there is no rate limiting or IDS in place.
NetScaler issues - some NetScaler versions appear to reject SSL handshakes that do not include certain suites or handshakes that use a few suites. If the test is failing and there is a NetScaler load balancer in place, that's most likely the reason.
Unexpected failure - our tests are designed to fail when unusual results are observed. This usually happens when there are multiple TLS servers behind the same IP address. In such cases we can't provide accurate results, which is why we fail.


Does that file actually exist? Have you manually deleted or renamed anything within /etc/letsencrypt?


Please show these four (you can post replies individually if you like):
sudo certbot certificates
grep -Eri 'servername|serveralias' /etc/apache2
grep -Eri 'SSLProtocol|SSLCipherSuite' /etc/apache2
netstat -pant | grep -i listen
