Topic: [Solved]No https connection possible from outside my LAN

[Luxed]

EDIT: Read the answers to find out what was causing the problem. In short my ISP is doing something on port 443 with their router/modem, I can't do anything about it, so I use another port.

Hey everyone,

I am trying to configure my Apache 2 site ( version 2.4.18 ) to have a secured connection, my server is in my house and it is running Ubuntu Server 16.04.
I use the Certbot program to get my certificates. I know they work because I can connect locally (from another computer on my network) to my server and the connection is secured.

This is my VirtualHost config:

The solution I found is to change the port to 444.
It works, but isn't what I want, I don't want to see a port.
Can my ISP be the one blocking the 443 port ?

error log say anything about your attempts to connect
if not, it may be getting intercepted by your isp which seems odd if 80 is open.

Shaw? I've seen folks on Shaw having this problem.

http://www.corentinbrunel.ca:443 gives a 404, meaning whatever server is answering port 443 it's answering with http not https.

Are there any other vhosts for 443 w/o SSLEngine On set in them?

Try forcing 443 to https:
Listen 443 https

Have also seen folks claiming this worked for them

As I said in my response earlier, I actually found the problem.
Upon further investigation, it seems like my Router/Modem is listening on that port, because no forward to port 443 is present now, so nothing should be listening, yet something IS listening on that port. What ? I don't know.

My quick and dirty solution is to redirect everything from port 80 (http) to https port 444 like this:

This issue may be related to firmware update, updating the firmware generally resolves such kind of issues if you are using netgear or similar routers, proper reconfiguration after the update is important at the same time.
