There indeed is something wrong with your SSL setup:
$ openssl s_client -connect socials.sk:443
140493201290432:error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure:../ssl/record/rec_layer_s3.c:1544:SSL alert number 40
no peer certificate available
No client certificate CA names sent
SSL handshake has read 7 bytes and written 302 bytes
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported
No ALPN negotiated
Early data was not sent
Verify return code: 0 (ok)
Would you mind, setting your SSL mode at Cloudflare to “None”, wait 5 min and then turn it to “Full (Strict)”?
Pls tell us when you’re done.
Also, I don’t think your Apache is responsible for this, but something went wrong at Cloudflare or your configuration there. Cloudflare seems not to have any SSL Cert for your domain.
But then you cant proxy the DNS and not provide any other SSL Cert at Cloudflare. If you force Cloudflare to disable it’s universal SSL and set it to SSL it will disable it. Pls do not change this setting, unless you are unproxied
Encrypted version of your site still does not work, btw but the unencrypted version is. I don’t know what else settings you changed, but just turn all good stuff with SSL on and wait untill Lets Encrypt validated, then it should work again.
No, your server is first place does not have anything to do with the connection to Cloudflare. After the connection to Cloudflare is established, then the connection from Cloudflare to your server comes into play.
