I have been experiencing an irritating issue, and I don't know the exact cause. I'm not sure if it's BM or my ISP. The issue is: You can be surfing along from page to page and all of a sudden, it stops. If you wait about 30-40s, you get this error:

Status : 504 Gateway Time-Out
Description : Lost connection to origin server.
Note : If necessary, please contact your Systems Administrator for resolution.


Internet Explorer cannot display the webpage

Most likely causes:
You are not connected to the Internet.
The website is encountering problems.
There might be a typing error in the address.

What you can try:
Diagnose Connection Problems

You can then click "refresh" and the page comes up with no problem and you can continue surfing until it happens again. If you try to open a new tab (IE7) it just sits there with the icon in the tab spinning until it times out. Most of the time, if you close the browser and reopen it, you can continue surfing if you remember where you were. This is a pain if you have multiple tabs open to different sites. Sometimes, IE7 will just freeze so that you cannot open new tabs at all. (That's usually if you click too much after it stalls.)

Does anybody know what could be happening?

I'm running NW6.5sp7 and BM3.8sp4.

Thanks in advance.
