You can find out a little more about ICMP Destination Unreachable here:
It could be caused by a number of things. For example there could be a
firewall (or router with ACLs) which is preventing a packet from being
received/forwarded and if the firewall had an option enabled to notify
the sender of this blocked port packet, then an ICMP type 3 code 3
packet would be sent out to the initiating IP addr from the firewall.
