Centos 6 Multiserver setup. lets encrypt is working for many years, Also today it created 4 new certificates for 4 new sites withoud any problems. But: I have one domain that stopt working. The 443 section is gone in the config. When checking letsencrypt it is not creating the 443 section. When only checking SSL, create a self sign certificate it is working. Treid to remove the letsencrypt files for this domain. Then a new certificate is created. The symlinks in /domein/ssl is created. But not the 443 section :-( any idees?
The 443 section is missing makes me suspect the certificate creation fails for that domain. Use this to find out why or rule this error out: https://www.howtoforge.com/community/threads/lets-encrypt-error-faq.74179/
like i said. Letsencrypt is working. The cert is there. I changed the 443 now manualy so that the domain is working again.
The link @Taleman posted contains instructions to find out why it was not possible to activate port 443. Please follow them step by step to find out why ISPConfig was unable to activate the cert. Common reasons are: not latest ISPConfig version, Not latest Certbot version.
again it is working for all other domains but not for this domain. Letsencrypt logs says everything is created "Your cert will expire on 2020-04-28." ISPConfig is up to date ISPConfig 3.1.15p2 ispconfig wasnt in debug mode so i cant see why ispconfig didnt do what it should be doing But i fixed it manualy
It is possible that its stays working for older domains but will not work for newer ones if certbot or ispconfig are not up to date and you won't be able to edit this website anymore until you find out what the reason is and fix it.
Then you didnt read the tread. "lets encrypt is working for many years, Also today it created 4 new certificates for 4 new sites withoud any problems." This domain in question had a working letsencrypt certifcate. Somehow that got broken Letsencrypts was turned off in the controlpanel and i cant get it back on. But in the back averything is working but not the 443 part. So somehowe somewere there is a hickup that ispconfig deleted the 443 part. It is working if i create a certificate in the panel But not with letsencrypt certbot version: 1.1.0
I just posted an example for one possible reason when SSL can not be turned on. The instructions from the FAQ will help you to get the issue sorted out.
