[CLIENT] Login Client doesn't allow me to log in.

Since the Snowdown has started I have been trying to log in to one of my three accounts. Everytime it says that i can not log in because of a connection error. I have only been able to log in once coincidentally so it is possible yet I could not recreate my success. I have uninstalled, tried to fix the patcher, looked on the boards, reset my router, changed the settings on my router but nothing works. I believe it may be the location i am at (which has been the same for a long time), an application on my computer that could be disturbing the connection, that my accounts may be online and i just can't access them, or any other reason. Also when i exit out of the failed attempt it adds a background process when i check task manager. I am unable to close the background process.

Thank you for the read riot. Sincerely, Sugary Delight
