What is the issue you’re encountering

I have subdomain abc.biz, then I want to create DNS jox.abc.biz and I want to appoint to my Public IP (xxx.xxx.xx.xxx:2086). I already config the port so it support with http cloudflare port. In my public ip address it still http, but why when I access jox.abc.biz it wont started. But when I access directly my public ip addres with port 2086, it succeded. But why in cloudflare is not success?

Hi there,

You do not have any firewall rules (on your origin side) that are allowing your IP where you are testing from, but possibly denying other IPs?

Confirm on your origin you have allowed Cloudflare IPs? - IP Ranges

If you believe this is all configured correctly, then I would need to know the domain name and hostname thats impacted in order to run some tests to advise what we’re seeing. I can keep the IP address censored, but would need the zone/hostname.

regards,

Firewall rules on my server is disabled,
How to allowed Cloudflare IP’s on my origin? I don’t know how, I’m really sorry I’m newbie on this DNS and SSL things
For the domain name is e-inv.newarmada.biz and hostname is newarmada.biz (is that right?).
In the SSL conf in my origin, the default virtual host is 443 and I used Origin Server (SSL Certificate - .pem and .key) from cloudflare.
I do hosting on hostinger and in the hostinger side I also import SSL to my e-inv.newarmada.biz into Hostinger SSL Installation

Hi,

You mention your virutal host is configured for port 443, do you have any virutal host configuration that allows port 2086?

regards,

the configure is in SSL that I want to install from origin, but it failed it said that the certificate is invalid. In that configure, I used virtual host with port 443. But, I can access my Public IP in xxx.xxx.xxx.xx:2806 (it still http).

Im sorry if you’re not understand what i’m saying

Ok - that makes sense - port 2086 is a HTTP port, If you want to use SSL HTTPS via Cloudflare you would need to use port 2087 - Network ports · Cloudflare Fundamentals docs

When you accessing the site jox.abc.biz - are you accessing it over http or https?

Are you attempting to access it like this https://jox.abc.biz:2086 ?

Yes, beacuse my ip public is still http so I used port 2086. Then I want use SSL in my subdomain that already HTTPS via cloudflare (web)

I try to accessing http://jox.abc.biz:2086 is success. Then cloudflare say that 2086 is HTTP port that supported by cloudflare. So, can I access just http://jox.abc.biz without type the spesific port (2086)?

Then I try to access https://jox.abc.biz:2086 it said “ERR_SSL_PROTOCOL_ERROR”

My goal is, I want to access just https:/jox.abc.biz
Can I achieve that? And what spesific steps I have to do? Because I still a newbie in DNS and SSL case
