Error Message
ERR_SSL_PROTOCOL_ERROR
Other Information
I am using free hosting plan and have a problem setting up the SSL/TLS.
I generated a new “Let’s encrypt” certificate using the https://app.infinityfree.net/ssls tool and got a private key and certificate. Successfuly uploaded the key and the certificate in the cpanel. However the when I tried to open my domain https://www.a11i.eu with Chrome I got the following error: ERR_SSL_PROTOCOL_ERROR
I tried to diagnose the problem with openssl
openssl s_client -connect a11i.eu:443
CONNECTED(00000003)

I verified that the private key is 2048 bits (with openssl rsa -in private.key --text -noout).
I tested the certificate inside local nginx and hardcoded ip address of a11i.eu in /etc/hosts, and Chrome recognize the certificate as valid, so at this point I think the private key and the certificate key are generated correctly.
What could be the problem? Is there any additional step that I need to do in order to configure HTTPS?
Thanks
