Since about evening time on 9/12, I've been having connection issues with XBL. Ever so often I would receive the 8015190E error. Upon attempting all of the solutions for this error on the XBL support page, I've found that none of them worked. I even contacted support with little to no luck, too. My Microsoft account didn't state that my account was blocked, or anything of that nature. I've cleared the system cache from the hard drive. I even deleted my profile to see if that was the issue, with no luck, of course.
When I tried to at least connect to XBL to re-download my profile, I would get a 'Can't connect to XBL' error, with no specification as to why or even a specific error code. I was only recommended suggestions, which suggested a modem/router shut down/restart as well as port forwarding. I know for certain that port forwarding isn't an issue, especially because I've been connecting to XBL with no problems for at least the past month and a half with default router settings. A restart was applied to my router, and I even reset the network settings to default on the console, with no luck.
I'm not sure if this has anything to do with the issue, and whether or not this could be the culprit, but one of my friends downloaded his profile to my console, and we were playing games just fine; however, this was two weeks ago, and if this were the problem, I would assume that the problem would have started from the moment he signed in with his gamertag. I've told him to go over the same diagnostics on his side, such as signing into his Microsoft account, making sure his account wasn't blocked, and I even deleted his gamer profile + his items, also with no luck.
There was an additional thread somewhere that advised turning off the console, taking the hard drive, then boot the console without the drive, turn it off, then boot it back up with the drive in place. I've also tried this solution, with no luck.
I know I haven't recently applied any updates to this console, as all updates have opened in another window and asked before pushing an update for the XBOX. Nor have I received a request asking to apply an update in the past week that this problem has been persisting.
Is there anyone that can assist me with this issue?
