Hello,
there might be millions of reasons, from slow connection, to maintenance works being done usually on weekends.
You should just follow the steps above.
Our servers are programmed to recover themselves automatically, so if you fail to connect and fail to start the server via mystandard, than it means main server is stuck, and probably it needs to auto-restart, it takes 30 mins +-. So you should try later.
