Error signing into xbox live

I’ve tried reinstalling the game, deleting the settings folder, and checking my firewall settings but there seems to be no solution to this issue. Every time I launch MCC, I get this error. The game doesn’t even ask for my Xbox Live account information, it just says “error signing into xbox live”. This seems odd because the Xbox Live website claims that all services are working properly. Not sure what to do next. I’ve bought the entire MCC today. I now own all of the games but am unable to even get passed the start screen because of this issue. Help please?
