How to correctly add a rule for https requests in iptables?

Question

iptables

Can the absence of a rule for https requests in iptables affect the processing of these requests?
If it does, how to add the rule correctly?

Now this is the situation, the server does not see https requests, at first it sinned on nginx, but with the help of netstat it determined that the nginx worker is listening on port 443 normally.

I checked the port with nmap from the outside:

Host is up (0.049s latency).
PORT STATE SERVICE
443/tcp filtered https

Answer 1

iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
