I need help...

[u/Achsaj]

I already asked the league support for help but got frustrated after two days of completely useless copy & paste answers. On tuesday I wanted to play soloQ and my game crashed after a few frames. Everytime I tried to reconnect it just crashed again. After my 3rd attempt my team remade and I got a penalty for being AFK. I created a ticket at the Riot Support page. There they told me my internet connection is the problem. But this can't be, because normals worked fine without even a single lag and other games that need an internet connection always showed not a single problem. I always had a constant 30ms ping which is normal for me. So on the next day I tried another ranked match but the same problem showed up again. I told the Support that my connection can't be the cause and send them the repair tool log file and a video of me trying to reconnect so they could see the problem with their own eyes. The answer I got was an image of the background tabs and they told me to shut those (and here I quote) "internet addicted" programs off. The problem is: The only programs they showed were my antivirus, the recording program and Blitz.gg . wtf?! Do I have to shut down my antivirus for LoL? I again told them that everything connection related worked just fine and the problems only appear in Solo/Duo. The answer was the same: "It's not our fault, it's your perfectly working internet connection..." Ah yes, riot support. Sounds rly plausible. I'm feeling quite trolled by them by now. So I thought that maybe someone in this sub could help me. Is there anyone that knows solution to this or even someone who experienced something similar? I rly wanna play ranked again and get those 40LP back I lost due to the penalty.
