Your connection to the game has been lost [Error: 42]

[Sir Owl]

I bought the game 3 days ago and i have a problem that it's getting more and more frustrating. When i try to join any online match (with party or alone) the game freezes in the loading screen and a few seconds later it gets me to the main menu saying "Your connection to the game has been lost [Error: 42]". This problem was only happening with some matches at first, but now i cannon join to any online match, no matter what i do. I might say that sometimes it seems the game disconect me while i was playing because suddenly in the main menu my progress was not saved causing that any changes and matches not count and i lost that progress.
I was reading a lot of posts in this forum and the official RL forums, and i did every single thing that the people suggested to the players that are in the same situation like me, and i tried some things of my own:

I played the game with low and max graphics and resolution; in window and full screen; i have not antivirus; disabled firewall; setted high and low priority; analyzed with avast and malwarebytes for virus search, no virus; cleared registry with Ccleaner, also used the clear tool for navigators and programs; turned on and off the steam cloud sync; verified local files with steam; disabled "Offline mode" of internet explorer; reinstaled the game; i have all drivers up to date; turned on and off the "talk to speak" option; setted the connection options of Rocket League to Low, Medium and High, also the input buffer in other modes; and probably other things that i'm missing right now.

My specs are:
-Motherboard: Asrock FM2A58M-VG3+ R2.0
-CPU: AMD A4-6300 Dual Core 3.70 Ghz
-RAM: 2 DDR3 4GB (8 GB total) 1596.8 Mhz
-Graphics: I don't have graphics card... Included in the board: AMD Radeon HD 8370D
-SSD Kingston 240 GB (Acquired 2 weeks ago, it's practicaly new)
-OS: Windows 7 64 bits

I only have this problem with THIS game, and i bought it for me and my girlfriend and it's frustrating that i cannot play with her and my friends :c They don't have any problem with the game, and i can't see what is the problem here... Please, help D:

You could check your connection requests time out sometimes, which leads to the disconnection from the game, make sure your cable doesn't contain any scars or cuts. You could also try this command to check your connection ping :
Open Run from the start menu > ping {LINK REMOVED}www.yahoo.com -t
If it says request timed out continuously, then there's a problem.

Thanks for commenting. I have done the test and my connection doesn't have any problem. My pc is directly connected to the router via cable. I play another games like League Of Legends and it never gives me more than 50ms in normal situations.
