In game disconnecting

So I was playing a normal game with a normal ping 119ms then when I get close to an enemy the game just decides to disconnect me for a few seconds. This happened to me twice already and I swear it is not my internet at fault here. When I restarted the game it went back to normal further proving that it is not my internet at fault but the game. I'm just saying this in case I get reported and banned from the game because we lost that game. Pls fix this RIOT so others won't experience this again.
