This has started happening to me a couple of days ago every single game. I have to restart the client atleast 4 times to eventually connect tot the match in progress. Sometimes i will connect at 20 seconds in, others 2-4 minutes in. My connection is fine as i can play anyother online game without a single problem. I tried reinstalling the client, flushing my DNS, disabling firewall, running as admin, running without admin, i reset my router, reset my computer, I tried using 188.8.131.52 DNS, i still haven't found a solution, and every thread i have been on there is the same old answers from riot help staff "Can you send the Error logs" & "Can you go through the troubleshoot guide", look, none of these solutions work. Give us an actual solution.
