Checked it out. I ended up having a WAF rule blocking non-US traffic.... Given Beehaw is US based, the fact that I was mostly getting posts from this instance makes a lot of sense now. Thanks again
I was using CF initially for proxying, but noticed some weirdness with federation. I would only get updates from Beehaw, but lemmy.world and other servers' updates wouldn't come through. As soon as I dropped the proxy and restarted the server, my instance got flooded by updates. I'm really not sure where to start debugging, so I've kept it off for now
