ClientSidecache read Connection Failed

I Don’t know what is happening. Yesterday is everything was working fine, but the next day I load into StarCraft 2 and ready to play some arcade with friends it says ClientSidecache_Read_Connection_Failed. I then tried to play Normal but the same thing happened. It still didn’t work when I restarted my Computer or Reinstalled StarCraft 2. The only thing I am able to do is Campaign. I am not able to play arcade, Coop, or Normal StarCraft 2

Hey, Cookie! Let’s the the following:

If it continues, could you gather a WinMTR file until the problem occurs for 10 to 15 minutes? Copy and paste the text file created and paste it between two ~~~ like so:

If you have issues pasting here, use Pastebin and post the end of the link. (ie. 123456 for pastebin.com/123456)
