connection lost

[R4yd3r]

no other recent threads, i'm gonna start one.
Ever since the rocket pass i've been constantly being disconnected randomly from matches (2 matches where i was actually winning by a long shot). I get an error saying: "Connection lost - No reservation found (Error 58)" I know its not my internet because as soon as it happened i checked my phone internet and the internet worked just fine, what does this mean and how can i fix it? thanks for reading.
