Hi dears,
unfortunately, my website [http://specknz.me/](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
nginx
```
How could be it sort out without touching the Snapshot on the Digitalocean?
Thank you.

SSH inside and do the tree magic phrases:
```plaintext
cd /var/discourse
git pull
./launcher rebuild app
```

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

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

What does

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.

I went through this tutorial [https://www.digitalocean.com/community/tutorials/how-to-install-discourse-behind-nginx-on-ubuntu-14-04#prerequisites](https://www.digitalocean.com/community/tutorials/how-to-install-discourse-behind-nginx-on-ubuntu-14-04#prerequisites) 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 │

And didn’t get a response similar to this:
Let’s Encrypt Output
IMPORTANT NOTES:
- If you lose your account credentials, you can recover through
e-mails sent to [sammy@example.com](mailto: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.

Ups I missed it 🙂
I’ve resized the Droplet to 1Gb by the using SWAP and tried to rebuild it, but it didn’t help me. However, yesterday I rebuild it successfully.
