Error using letsencrypt with Shiny Server Pro

Question

I am trying to configure Shiny Server Pro with a SSL certificate from Letsencrypt. I follow these commands to create my certificate as described here: https://certbot.eff.org/#ubuntuxenial-other

sudo apt-get install letsencrypt
sudo systemctl stop shiny-server
letsencrypt certonly --standalone -d pbisny.org -d www.pbisny.org

I add this line to /etc/shiny-server/shiny-server.conf

 ssl /etc/letsencrypt/live/pbisny.org/privkey.pem /etc/letsencrypt/live/pbisny.org/cert.pem

And start the server.

sudo systemctl start shiny-server

I then get this error:

Job for shiny-server.service failed because a configured resource limit
was exceeded. See "systemctl status shiny-server.service" and
"journalctl -xe" for details.

Here are the details of systemctl status shiny-server.service

shiny-server.service - ShinyServer

Oct 22 12:29:19 pbis-pro systemd[1]: shiny-server.service: Failed with result 'resources'.

I will admit, I am not a sys admin. Any help figuring out what this error means is greatly appreciated.

if you have Pro you're likely to get fast support from RStudio support channels. — hrbrmstr, Oct 22 '16 at 14:50

Finally figured it out. The following commands create the certificate:

sudo apt-get install letsencrypt
letsencrypt certonly --standalone -d domain.com -d www.domain.com

Here is the server section of my /etc/shiny-server/shiny-server.conf file:

server {
  listen 80;
  location / {
    redirect "https://domain.com" 302 true;
  }
}

server {
  listen 443;
  ssl /etc/letsencrypt/live/domain.com/privkey.pem /etc/letsencrypt/live/domain.com/cert.pem;

  # Define a location at the base URL
  location / {

    # Only up tp 20 connections per Shiny process and at most 3 Shiny processes
    # per application. Proactively spawn a new process when our processes reach 
    # 90% capacity.
    utilization_scheduler 20 .9 3;

    # Host the directory of Shiny Apps stored in this directory
    site_dir /srv/shiny-server;

    # Log all Shiny output to files in this directory
    log_dir /var/log/shiny-server;

    # When a user visits the base URL rather than a particular application,
    # an index of the applications available in this directory will be shown.
    directory_index on;
  }

}

Last, restart the shiny server.

sudo systemctl restart shiny-server

I have had such an issue, it usually occurs when a curly bracket at the end or a semi colon is missed out in the config file.

This error message:

Job for shiny-server.service failed because a configured resource limit was exceeded. See "systemctl status shiny-server.service" and "journalctl -xe" for details.

appears when there is an error with the conf file /etc/shiny-server/shiny-server.conf.

To check the details of the error that triggered this message, check the logs in /var/log/shiny-server.log. One line should have someting with Error loading config: followed by the details that will help you fix your config file.
