I was looking though the forums to find a post that has similar situation as me and I found this post.
My internet connection speed test is:
232.7 Mbps download
11.2 Mbps upload
Latency: 8 ms (L.A Server)
I followed the "CHICKEN" article deleting my "Download Cache" on Steam and restarting my modem. I even went as far to call my internet provider and asked them to restart my modem from their side. It worked for one session of game-play and then switched to another game. Later that day I deiced to jump back on D2 and was presented with the same "CHICKEN" error code. I also went to re-verify my game files and re-install my game entirely and the issue still persisted. I just wondering if this issue will be fixed at least before the "Beyond Light" DLC comes out.
Yeah i have seen the influx of chicken posts, but not a single one has been addressed beyond what is talked about in the chicken article (players having bad connection to bungie servers) which isnt what causeing so many people with good connections to get this error.
