My team is having an issue where our website's websockets are coecting some people to our website just fine, but others can't. When they login they get a coection ended error but others get no error at all. We thought it was a bandwidth/data issue, but we aren't completely sure, so we plan on using a fallback until we get a solution. Can anyone help with a solution for this? We're using Linux, sintra websockets and Nginx. Sever setup.

Also some interesting notes that it works on Chrome and Oprah on my computer but not Firefox.

Error I could grab. Firefox can’t establish a coection to the server at wss://budokai-online.com/arena.

ws = new WebSocket('wss://budokai-online.com/arena');

Tested on all broswers.
