@dunlix I'm already using a custom theme, but my site has it's own login system where the user is shown logged in at the top -- this would not be possible if i put it into a nodebb theme. Also session-sharing and iframe is already working perfectly.
Changing main domain to https + paying the cost
I have opened port 443 in my server and when I use telnet ip 443, it works fine, but when I enter https://mysite.com it shows me ERR_SSL_PROTOCOL_ERROR. And when I use https://ip it takes much time to load and then show me it can't be reached.
Can anyone help me regarding this issue? I will pay its costs in order to run my website with SSL.
It is VPS and only one website is hosted.
And I want to be sure that if I update/upgrade nginx in the future, the settings will not be replaced by the default ones.
Thanks in advance
@inna you'll want to generate an SSL certificate with Let's Encrypt (you can see the directions on their website)
