Problem with SSL on TLD .dev

Website, Application, Performance Getting Started

Help me guys I have a weird problem with my website: I’ve set everything, but it doesn’t work. My settings:

SSL/TLS
SSL: Full
Edge: +
Origin: +
Always use HTTPS: +
HSTS: -
Origin pulls: +
Min. TLS ver.: TLS 1.0
Opportunistic Encryption: -
Onion Routing: +
TLS 1.3: +
HTTPS rewrites: +

Sometimes website starts working when I Purge Cache in CF.
My website: https://yerofey.dev/
Sometimes it works, but most of the time not working.

For me the call works fine.

$ curl -I https://yerofey.dev/
HTTP/1.1 200 OK
Date: Sun, 15 Sep 2019 06:38:52 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
Expect-CT: max-age=604800, report-uri="https://report-uri.cloudflare.com/cdn-cgi/beacon/expect-ct"
Server: cloudflare

This usually is an SSL 1.3 issue, however you seem to have set 1.0 as minimum. Can you run cURL with the -v parameter as well?

Seems to be the same as c - SSL_CONNECT fails with SSL_ERROR_SYSCALL error - Stack Overflow

Make sure your operating system is on the most recent version (cURL, libraries, etc.) and should that still not work, you could try to force a version with --tlsv1.X (X for the TLS version, 1 or 2).
