So I re-subbed to Xbox live on my Xbox 360 after a long hiatus. I also bought TK and downloaded all of the compatibility packs [i](8 years later)[/i]. I immediately had continuous networking issues both for destiny and Xbox Live. I started on wireless internet, but once the issues emerged, I switched to hardwired internet. So, I started the long, seemingly arbitrary, journey of fixing my network. The Xbox Live error code I got in conjunction with the Caterpillar error, is the 8015190e error. [b]What I've done[/b] For 8015190e error code. [i](As per Xbox live support page)[/i] [u]Solution 3:[/u] Deleted Profile - Cleared cache 3 times - Unplugged Xbox and router for over a min - Plugged it all back in - Redownloaded profile. [u]Solution 4:[/u] Set up static Ip for Xbox 360 console - Set up port forwarding for my technicolor router - set the Xbox 360 console Ip address to be the DMZ host. Furthermore, I do have Upnp mode activated. Meaning my NAT type is not STRICT. What are my last resorts to fixing this error? What information have I left out to better solve this problem?
