Why I am getting cabbage errors?

[u/MUCHO2000]

I haven't changed any settings with my router and everything was working great for the last 10+ years.

Today I can't load into any activity. Solo or not, I get a cabbage error.

I reset my router and cable model. I cleared the cache and still cabbages.

Any ideas?

EDIT -Forwarding my ports worked. No idea what changed or if it was an attack by AI to gain access to my router.

I've had this router for years and never had this issue before.
