When signing on my Xbox Live account today and updating my security on the 'Add Security' screen that pops up, I receive the following error message;
'Sorry, there was a problem. Please try again later. Code: 80150100'
I looked on the Xbox Support website to see if I was able to find a reason/resolution to this message but I only came across a a web page that wasn't relevant to the problem I was having (it was related to receiving the '80150100' code when trying to access the marketplace).
Then I thought that the issue was with the connection to Xbox Live so I signed out of my Xbox Live account and tested the wireless connection to my router and the test that it performs, came back as successful for all the areas you can pass on.
I know this issue is not a problem with my profile because I changed my password for my account today and it synchronised with my profile immediately as I was able to use the new password straight away!
Also, the weird thing I found was that when I am not signed into my Xbox Live account, it can connect to Xbox Live and when I'm signed into my Xbox Live account, it can't connect to the server.
Any help would be appreciated!
