As the title says, I am constantly getting disconnected from Xbox live. This only happens when I play Destiny. I can watch Netflix and play other games online no problems. But I can not even log in and go to the Tower or any mission. Either during the loading screen or as soon as I land on a planet I get an error message and am then disconnected from Xbox Live. Sometimes I can maintain connection for about 20 minutes and then I am disconnected. I have seen the following error codes when this happens: Caterpillar and Hawk are most common, followed by Weasel, Viper, JackRabbit, and Ferret. In spite of all this, I am rarely disconnected when playing with other players. I can raid for hours without getting disconnected once. But as soon as I try to do anything on my own I am disconnected. I have tried all suggestions on both Bungie's help page and Microsoft's. I have tried port forwarding my router and setting a static ip for my xbox but upon doing so I am told that my NAT is set to strict. My ISP is Comcast.
