I'm getting it in pit and crucible non stop. There's nothing wrong with my router.

Hey there! [url=https://www.bungie.net/en/help/article/46243]CABBAGE[/url] occurs when there is a security feature within the router that is preventing you from playing Destiny 2. To resolve this, you need to inspect your router manual to use the solutions stated in the article. If that does not help, what is the brand of your router/modem? CABBAGE and LETTUCE errors usually occur with Thompson and Technicolor routers.

Yes dame here

Cabbage is a completely client-side error, meaning your Destiny 2 is telling you that it can't work properly because it finds that one of the network port it needs to use is not available, probably due to your modem/router FW blocking it.
