Attempting To Recconect

Hey guys i wanted to talk about client issues im getting since over 3 months now and im sure im not the only one who gets these kind of problems, so whenever i play with my friends we talk on discord or in league voice chat and out of nowhere i get a flushing messege on the top of my screen "attempting to recconect" but the fact that i can still hear my friends talking is kinda bothering me cuz im sure my internet is preety decent. When i said "attempting to recconect" im sure u guys know what im talking about, but if u dont lemme explain. So when u lose ur internet ur connection or internet connection is insuffisent this messege would appear but the fact is that im never having these kind of problems with other games/apps is quostionable, and im using wired net as riot employe reccomended so i shouldnt get these kind of problems. I called my provider to ask them is there something wrong and they said they will do a complete test, as they did so they asked me does this happen only in league and i said yes and they immediatle knew what is going on. They told me that my provider (Sfr) isnt in "collaboration" with Riot Games they didnt said why so im asking why im constantly getting these "attempting to recconect" msgs?

Every kind of help would be apreciated and sry for my bad eng. Kindness Regards.
