AresMUSH
A New Breed of MUSH Server

Troubleshooting Issues

Sometimes things go wrong, and you’ll get the “Sorry! The code lost its mind while executing a command…” message or the Sad Picard screen on the web portal. This article will help you diagnose the problem.

If the information below doesn’t help you, you can always ask for help on the Ares Forums.

Log Files

The first place to check is the game log. This will help you pinpoint the exact file and line number where the code failed. See Using Log Files for help.

Debug Mode

For tricky issues - especially during development - it can be helpful to run the game in Debug Mode.

YAML Issues

The configuration files use YAML, and there are several common issues that can result from trouble with your game configuration. Often you’ll see an error message like “Error reading YAML from fs3combat.yml…”, but any error that happens right after you changed your game configuration should make you suspect a YAML problem. See Troubleshooting YAML for more details.

Server Won’t Start

Sometimes you’ll get a ‘connection refused’ error in your MU client or a ‘This site can’t be reached’ error in your web browser. When this happens, there are a few things to check:

  • Make sure your hostname is correct and your DNS is set up. Ares can’t start if the hostname is inaccessible, and you’ll see an error in the logs like “no acceptor (port is in use or requires root privileges)”.
  • Try starting the game in debug mode using bin/devstart instead of startares. This will run until you hit CTRL-C, and you will see log messages live on your screen.
  • Try changing your hostname (in server.yml) to ‘localhost’ or the machine’s IP address to rule out DNS issues.

Database Issues

If your game can’t connect to the database you’ll see an error like: “Error connecting to database. Check your database configuration.” Here are a few things to try:

  • Check your database config file (database.yml) and make sure you have the correct URL and password. You can compare these values to the ‘port’, ‘bind’ and ‘requirepass’ parameters in your redis configuration file. In the standard install, this file is located at /etc/redis/redis.conf.
  • Make sure your database service is running. You can use the server shell command service redis-server status.

Web Portal Unavailable

If you get a ‘page not found’ error for your web portal, here are some things to check:

  • Make sure that your web server is running. You can use the server shell command service nginx status.
  • Make sure that the website code successfully deployed to /var/www/html. You should see index.html and other files there.
  • Make sure your web server has a site configured to use that directory and the web portal port in server.yml. In nginx, this site configuration should be in /etc/nginx/sites-available/deault.

Web Portal Can’t Connect to the Game

Sometimes you’ll get a Sad Picard message saying the web portal can’t connect to the game.

  • Try a force-refresh in your web browser.
  • Make sure the game is actually running and you can connect to it with a MU client.
  • Make sure there’s a symbolic link from your web portal directory to your game directory. If you do ls -l in your /var/www/html directory, you should see an entry like this:

    ares ares 24 Apr 2 01:01 game -> /home/ares/aresmush/game

Web Portal Sad Picard

Most of the time, problems on the web portal are actually problems in the web request on the game side. You’ll see those errors in the game log and troubleshoot them in the same way you would any other game error. Occasionally, though, the problem will be in the web portal Javascript code.

  • Try a force-refresh in your web browser.
  • Troubleshoot using the web browser’s debugging tools. In Chrome, for instance, you can open View -> Developer -> Developer Tools to see the Javascript console, which will tell you the error.
