NSURLErrorDomain code=-1005 from GKLeaderboard loadScoresWithCompletionHandler:

Question

I am receiving the following error in a callback to loadScoresWithCompletionHandler:

Error Domain=NSURLErrorDomain Code=-1005 
"The operation couldn’t be completed. (NSURLErrorDomain error -1005.)"

Other calls to Game Center both before and afterwards succeed. (They operate on various threads). If have initialized the leaderboard request as follows:

GKLeaderboard *leaderboard = [[GKLeaderboard alloc] init];

leaderboard.identifier  = leaderboardIdentifier; // valid identifier
leaderboard.playerScope = GKLeaderboardPlayerScopeFriendsOnly;
leaderboard.range       = NSMakeRange(1, 100); // max. allowed range.
leaderboard.timeScope   = GKLeaderboardTimeScopeAllTime;

[leaderboard loadScoresWithCompletionHandler:^(NSArray *scores, NSError *error) {
    // ...
}];

What is going on here and how can I overcome this problem?

The calls to loadScoresWithCompletionHandler: are made from an operation on an NSOperationQueue whose task it is to issue requests for scores (I am interested in each localPlayerScore) to several leaderboards and wait for all responses. The first response already carries the error.

UPDATE -1005 denotes kCFURLErrorNetworkConnectionLost; the underlying cause is still unclear.

UPDATE If I send only a single request (instead of as so far typically 6 in parallel) I receive error NSURLErrorDomain -1001, which denotes kCFURLErrorTimedOut, or GKErrorDomain 3 ...

For some reason this alternative call does not lead to errors:

GKLeaderboard *leaderboard = 
    [[GKLeaderboard alloc] initWithPlayers:@[ GKLocalPlayer.localPlayer ]];

leaderboard.identifier = leaderboardIdentifier;
leaderboard.timeScope  = GKLeaderboardTimeScopeAllTime;

[leaderboard loadScoresWithCompletionHandler:^(NSArray *scores, NSError *error) {
    // ...
}];

Problem solved.
