Hi, currently having an issue where our network cannot access - https://box.com
We can access it by its IP (220.127.116.11) but this takes you to https://11.app.box.com
rather than box.com. We can also access the old site - https://www.boxcn.net/
and it works with any wildcard i.e something.box.com
Now sure where to go on this really. We don't have any content filtering on the firewall & I have tried open DNS and also going straight out from the firewall with a laptop plugged in, but it is exactly the same.
Only thing I can think of by looking in the Sonicwall logs is that it thinks it is some sort of attack. As you are going to one address but getting a different one back. The log we get is:
'Probable TCP NULL scan dropped 18.104.22.168, 0, WAN'
Anyone experienced this before or got any ideas ?
