Error Code 2124

If you come across an Error Code 2124 or experience issues with content not being displayed correctly, you may wish to forward the below information on to your school’s technical team and they should be able to check that everything is configured correctly.

Filter and Proxy configuration

If you are running a proxy server or content filter, you may need to configure the server/filter to allow through the following hostnames to allow the MangaHigh maths games to run correctly:

  • www.mangahigh.com (our main website)
  • images.mangahigh.com (which hosts the graphics and games for the site)
  • schools.mangahigh.com (where your students need to go to login)
  • support.mangahigh.com (our help/support site)
  • news.mangahigh.com (our news site)
  • api.mangahigh.com (not currently used, but may be used in the very near future)

Ideally, you should allow access to the entire mangahigh.com domain name using a wildcard (such as *.mangahigh.com) to reduce the chance of having to change your configuration later.

Some proxy/firewall software may also block set filetypes or “mimetypes” – please ask your network technician to ensure that the following filetypes and mime types are allowed through the firewall:

  • .html     text/html
  • .txt        text/plain
  • .css        text/css
  • .js           application/x-javascript
  • .jpg         image/jpeg
  • .gif          image/gif
  • .png        image/png
  • .swf         application/x-shockwave-flash
  • .xml        text/xml and application/xml
  • .amf        application/x-amf
  • .mp3       audio/mpeg
  • .amf       application/x-amf
