nginx https server logs

[foly]

Hello,

When I connect to HTTP site server log shows all requests.
I mean that number of requests is the same as log entries.

When I connect to HTTPS site (with Let's Encrypt, for example) server log
shows only first request.
I mean that I can refresh page again and again without new entries in server
log.

Is it misconfiguration? 
I have used some manual to setup Let's Encrypt with nginx.
