Hello there!
I havent found the answer to my question so Ive decided to create a new topic.
I have DOMAIN + SSL GATEWAY + VPS (everything hosted on OVH).
I can enter my domain url by HTTPS protocol due to SSL GATEWAY. The SSL GATEWAY than is redirecting to my VPS where docker container with nginx is running. Nginx has only port 80 opened. But somehow SSL GATEWAY is requesting to it by HTTPS (which I can see in nginx logs). Port 443 for HTTPS communication is not open on nginx. Can I assume that this solution is safe? Do I have to configure my nginx (open port 443 and generate new SSL certifacate) separately? Also what is important when I directly go into VPS IP I cannot enter by https port 443 which is obvious because there is only port 80 opened. Unfortunately I see it this way: connection between CLIENT => SSL GATEWAY is by HTTPS (its safe) but further communication between SSL GATEWAY and VPS is by HTTP and its not safe.
Thank you in advance for any help!
Cheers,
Tom
