ERR_SSL_PROTOCOL_ERROR with Letsencrypt

mdfrg · February 26, 2018, 1:56pm

Hello,

I have a problem with setting up Discourse forum with Letsencrypt SSL cert. For the sake of example, I will refer to my page as mypage.com.

THE GOAL:

I want to set up VPS where I will have wordpress blog working on blog.mypage.com, landingpage on mypage.com and Discourse forum on forum.mypage.com. I want to use nginx with mariadb and have Letsencrypt SSL certs installed.

THE PROBLEM:

When I enter the forum.mypage.com for the first time with “fresh” browser (cookies and history deleted, new profile) in chrome I have an error

“This site can’t provide a secure connection
forum.mypage.com sent an invalid response.
ERR_SSL_PROTOCOL_ERROR”

With FIrefox, nothing happens - the window is blank and page is not loading.

However, if I go to mypage.com FIRST, everything works as expected and if I THEN enter forum.mypage.com, the DISCOURSE FORUM LOADS WITHOUT PROBLEM.

THE SETUP:

Digital Ocean DNS settings are configured properly, i.e. they redirect mypage.com, www.mypage.com, blog.mypage.com, www.blog.mypage.com, forum.mypage.com and www.forum.mypage.com to my VPS IP. (A record). Record for mailgun are also set properly, as I receive registarion mails from my Discourse installation.
I use Ubuntu 16.04 DigitalOcean droplet where I installed newest stable versions of nginx 1.12.2, php 7.2.2 and mariadb 10.2.13 from maintainers PPAs. 2GB swap file is enabled as requested for Discourse.
I installed certbot using instructions from https://certbot.eff.org/. I used syntax certbot --nginx -d mypage.com,www.mypage.com,blog.mypage.com,www.blog.mypage.com,forum.mypage.com,www.forum.mypage.com
Here is my configuration files:

All files in /var/www are readable by www-data.

To set up Discourse I followed instructions from Run other websites on the same machine as Discourse

EDIT: added nginx log

Turn session tickets on in the discourse nginx file.

mdfrg · February 26, 2018, 2:56pm

Wow, that was easy! It works now. Following the nginx doxumentation: should I create ticket key ( openssl rand 80 > ticket.key) and then add ssl_session_ticket_key /path/to/ticket.key to the etc/nginx/sites-enabled/discourse? Is there any drawback from turning this on?

ThomasLewis · February 26, 2018, 3:35pm

I just turned it on, and it started working.
