Acme-Challenge on Apache 2.4 fails on some virtual hosts, but some not

I just posted this on #StackExchange: If you know the answer, please help me. :-) I need to update certificates for https://git.mxchange.org and https://searx.mxchange.org (which is some-why returning 403 on any requests).

Fixed, please refer to my own answer.

Let's Encrypt!

I have now installed a better #SSL certificate issued by #LetsEncrypt and with the help of this #python script: https://github.com/diafygi/acme-tiny

Plus I have used a largely expanded #shell script:

But now my SSL sites got rated with B by #SSLLabs because of an incomplete chain. I think I need to download the CA certificate and attach it at mine?

I also have (not yet reloaded) added DH parameters (DH = Diffie-Hellmann?) to my certificate parameters, I have read it will improve some security.
#SSL #LetsEncrypt #python #shell #SSLLabs letsencrypt security ssl
Yes, that was the case. I needed to include the certificate in my file.
