Discourse has stopped opening

Hi dears,
unfortunately, my website http://specknz.me/ has stopped opening and I don’t really know what has caused it. Also I’ve got an error:

502 Bad Gateway

How could be it sort out without touching the Snapshot on the Digitalocean?
Thank you.

SSH inside and do the tree magic phrases:

cd /var/discourse
git pull
./launcher rebuild app

Thanks Rafael, I’ve already rebuilded the app, but it still doesn’t work.

Connection to closed.

I didn’t understood the log, why the reboot after the rebuild?


I tried to open the website before and after the reboot, anyway it doesn’t work.

Please tail the logs. My bet is a wrong permission so start by tailing nginx log.

Unfortunately the access.log is empty. I found some logs through the error files.

What does

./launcher logs app

give you?

Our nginx logs are actually in /shared/log/var-log/nginx


Those emerg entries on the nginx log mean he’s not gonna run. This is a problem with your ssl setup, it is missing deparams.

I recommend setting up ssl again.


Unfortunately, it gives nothing.

root@discourse:~# ./launcher logs app
-su: ./launcher: No such file or directory

root@discourse:/# cd /shared/log/var-log/nginx
-su: cd: /shared/log/var-log/nginx: No such file or directory

Yeah, this is the problem. (“Emerg” = Emergency)


I went through this tutorial How To Install Discourse Behind Nginx on Ubuntu 14.04 | DigitalOcean to recreate SSL Certificate on Nginx for Ubuntu 14.04 and got a message.

root@discourse:/opt/letsencrypt# ./letsencrypt-auto certonly --standalone --email tamerlanium@gmail.com --agree-tos -d specknz.me

The program exe (process ID 1304) is already listening on TCP port   │
   │ 443. This will prevent us from binding to that port. Please stop the │
   │ exe program temporarily and then try again.

At least one of the (possibly) required ports is already taken.

And didn’t get a response similar to this:

Let’s Encrypt Output

  • If you lose your account credentials, you can recover through
    e-mails sent to sammy@example.com.
  • Congratulations! Your certificate and chain have been saved at
    /etc/letsencrypt/live/discourse.example.com/fullchain.pem. Your
    cert will expire on 2016-04-26. To obtain a new version of the
    certificate in the future, simply run Let’s Encrypt again.
  • Your account credentials have been saved in your Let’s Encrypt
    configuration directory at /etc/letsencrypt. You should make a
    secure backup of this folder now. This configuration directory will
    also contain certificates and private keys obtained by Let’s
    Encrypt so making regular backups of this folder is ideal.

Hmm how was your Discourse instance setup? Are you on the docker based install?

Yeah, it have been installed through the Docker instance.

Try following

to install a Let’s Encrypt cert instead


Sorry Guo, should I rebuild the Discourse container?

4. Rebuild your container

./launcher rebuild <container name>


Can you please try rebuilding?

Please SSH into your server and run:

cd /var/discourse
git pull
./launcher rebuild app


run ./launcher rebuild app
