Websocket.js.54 problem

Hi,

I’ve been using Forge for a while now and I work in a school.
Up until Christmas it was working fine for my D&D club, but now all of a sudden I am getting stuck BEFORE the log in screen to my server.
I’ve checked the console and it is showing 11 websocket errors.
I’m assuming this is school server related, but I just wanted to check there was nothing I could do before I took this up with our IT support as they have worked very hard so far.

Thanks.
