Months ago (8+ now) I ran into this error whilst playing valorant. What this error does is force quits you out of valorant mid game (whether its ranked or dm) due to a connection issue. It can happen once or twice in a game, and it happens every single game. After first encountering this error, I of course tried every means of fixing it with every known method from google, reddit etc. I've tried reinstalling Valorant and Riot Client, enforcing vgc, deleting all relevant files, and even factory resetting my computer. Nothing worked except two:
Buying a new pc or buying a new internet connection.
I'm making this post to spread awareness of this ridiculous issue, as it has made me quit valorant for months on end. Anyone else facing this issue and fixed it, good for you. For those unfortunate like me, I suggest either quitting valorant for good or buying a new router.
