Mid-match connection error

I have been having a lot of problems with this for the last week. I use a wired connection and I enter matches with 45 ms. Despite this, even though I win a match by a large margin in division rivals or champions, I am redirected to the main lobby due to the connection. I am sure that there is no problem with my own internet, I play other online games, but none of them are like your bad servers, I have a very smooth gaming experience. The connection error does not only occur in the middle of the match, it gives an error after most of the packages I open and I open the same package a second time. I will stop playing this game until I wait for my problem to be solved, it is a complete waste of time.
