High Latency Issue Xbox One
About two days ago, my latency jumped up to around 130-170 ms minimum on Xbox One, and it will fluctuate higher randomly. It makes the game borderline unplayable. I checked my internet connection to be sure that is was not the source of the problem and my connection was perfect. Before about two days ago, my connection was around 30-70 ms, and it was perfectly fine. I have already followed all of the steps.on the support page, and I still have the same problem; none of it helped.
It looks like I finally fixed the issue. It looks like I talked too from my ISP lied to me, and the ports were not actually open. Since I could not get into my router manually, I found a program online that opens the ports using the routers UPnP. I guess somehow the UPnP stopping working properly for some reason a few days ago or something like that. Everything seems to be fine now and latency is down to excellent levels.
