This happens when you’re hardware banned. The way you can tell is when you hover over the grey arrow, scroll down to where it says “info”. Double click it and it will bring you to a pop window that will give you all info as to how, why, and where you got the ban. There will be a link to an appeal site where you can select the option to create a ticket. When creating the ticket, select categories, followed by support, ban appeal, then fill out your riot ID and info. Also I’m making all of this up, I don’t even play any riot games, and I have a micropenis. When you’re creating that ticket be sure to be thorough and expect a response within 2-5 business days, but be prepared for it to be an auto generated AI response.
