Recently I've been having issues playing online. This is mostly in regards to Halo Master Chief Collection and Call of Duty Advanced Warfare.
On Halo MCC, I played for a few weeks with no issues, then all of a sudden, after one game I was unable to find any other match. It shows "Searching for players..." but after hours of letting it search or retrying I have played zero games. After going through many, many steps to rectify this, I was able to play two games, after which this all began again and none of my previous steps worked this time. On Call of Duty AW, every time I search all it says is "No Games Found."
I'm not sure why this is happening, but here is the results of tests, and the steps I have tried:
Xbox Live connection test shows everything is good. I can access all Xbox Live features besides online multiplayer in games.
Xbox Live Multiplayer test says that "Everything is good." and there are no problems with my xbox live multiplayer.
NAT is OPEN.
I usually use a static IP set up with port-forwarding for Xbox and Halo MCC ports. I have attempted using both static and dynamic IP addresses, and manual and automatic settings listed in network configuration. I have tried hard-resetting my Xbox multiple times, and resetting my router multiple times. I have used wired and wireless connections. I have tried moving my games from internal to external storage, as well as re-installing my games. I have used my DNS settings, and I have used the Google DNS settings. I have tried joining games while in a party with my friends (they find games easily by themselves, but if I attempt to play with them we are not able to find any matches).
Basically, I have tried everything possible that I can think of. Each time I try, my Xbox Live connection and my Xbox Live Multiplayer connection tests show that everything should be working, and my NAT shows as open unless I disable the NAT setting on my router. Because of my internet provider, my router can only act in bridge mode. My modem is a CISCO-DPC3825 and my router is an Asus RT-N66U Dual Band N900 router. Like mentioned above, this problem began out of nowhere. I have been able to play online games fine since my purchase of my Xbox one last year.
The only change I have noticed, is my reputation has decreased to "Avoid Me" due to circumstances beyond my control. (Flawed Halo MCC host-deciding architecture). I have made a post in the enforcement forum to have this undeserved reputation amended by Xbox staff. However, I don't think this would completely bar me from being able to find any online match.
If anyone has ANY suggestions.... Please let me know. This has been going on for 4 or 5 days now.
