Connection to server timed out (code:leaf)

Hello, I have had the same issue, ever since the masters patch Tuesday or Wednesday morning, I have been unable to play I have spent 8+ hours trying to fix the issue, and have talked to 3 people on the helpline who have refused to acknowledge it's an issue with them. There is nothing wrong from my side. Similar to the issue from January where people weren't able to play for 2 months. 
If anyone finds a fix to this issue, please let me know.
