Player not connected

[h3ntie]

Any time I try to change my rank with:
{
"lol": {
"rankedLeagueTier": "CHALLENGER",
"rankedLeagueDivision": "i"
}
}

I get this error:

{
"errorCode": "RPC_ERROR",
"httpStatus": 503,
"implementationDetails": {},
"message": "Player not connected"
}
Response Code

Even though i am in the client and it can connect with the internet ( I know this cuz u can still add friends to your lobby and communicate etc) even though your lobby says forever "connecting..." and the left side of your friends menu doesn't appear.

I am are there is a bug going around with the friends list and "connecting..." but am I doing something wrong with the code or is it a bug ?
