I'm using the USB720 modem. Since yesterday morning I have been getting a 504 gateway timeout error when trying to access my own website. Strange, huh? The thing is everyone else can see it fine, but I get the error every time. Using both the modem and my iPhone. I connected to a store's wifi yesterday and loaded my site fine. That makes it sound like an a problem with Verizon doesn't it? I have contacted my host site and they told me that it wasn't a problem on their end. I'm very frustrated because I can't even access my dashboard or anything. Any help or advice would be greatly appreciated.
