Problem with SSL on TLD .dev

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

SSL: Full
Edge: +
Origin: +
Always use HTTPS: +
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:
Sometimes it works, but most of the time not working.

For me the call works fine.

$ curl -I
HTTP/1.1 200 OK

Content-Type: text/html; charset=UTF-8
Connection: keep-alive

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?

➜ ~ curl -I -v

Seems to be the same as

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).
