I am having the same issue, only on PC. This has been happening ever since the 1.1 patch, it never did this in the previous 3 weeks I owned the game.
The option to open crates at the bottom left of the main menu does not show up, nor my credits and crafting parts at the top right. After a few seconds I get the message :
"We can't load the store offers. Please check your connection. Error code: 2,446"
After that message it says "Some online features are currently unavailable" beside the quit button on the main menu.
I can play the game in arcade and join multiplayer games. I tried playing both types for a bit but it made no difference.
I also notice the game fails to connect online at all sometimes when I load it, I have to click the Connect button at the top of the main menu. It will then connect online, but still with the above problems.
