HTTPS 443 not accessible to the outside world DOCKER

  • 772

Currently I have setup

docker with linux ubuntu 18.04

In my container reverent_ptolemy

contains the project of my api.

On my container

HTTP vhosts configuration is listening to 3021

HTTPS vhosts configuration is listening to 1250

and on my Host

port 3021 is mapped to port 80

port 1250 is mapped to port 443

enter image description here

In my host docker

I can access my api through HTTPS Curl

like this

curl https://<sub-domain>/api/login

enter image description here

But when I tried to access this from the browser

this gives me an error like this

enter image description here

PS:

Only http://<subdomain>/api/login is accessible from the outside world not the https

What could be the reason why HTTPS is only accessible on the host and container but not accessible from the outside world?

  1. First of all check iptables (if you allow https traffic) or directly add a rule on the fly (will not be available after reboot or iptables restart - this is just for test sake):

    iptables -I INPUT -p TCP --dport 443 -j ACCEPT

    Secondly, you were trying to use GET method for your API when most likely it only allows POST method.

    I solved my problem.

    First if you're trying to do SSL on your docker. Make sure your 443 port is forwarded. You may check your 443 port if it is open or closed
