Connect to iOS network when notified

Question

The following code usually works, but when you try to block the connection to the SSL port (-9806) is canceled.

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler { NSString *roomID = [userInfo objectForKey:@"roomId"]; if (roomID) { //tell firebase to update this conversation [self.fb updateChatRoomMessages:roomID withBlock:^(BOOL success) { /*code gets to here as I can see that with breakpoints, but before we get here we can see the SSL handshake error in console (only when phone is locked)*/ handler(UIBackgroundFetchResultNewData); }]; } else { handler(UIBackgroundFetchResultNoData); } } 

Now basically updateChatRoomMessages is trying to talk to firebase, but I assume the problem is with some kind of network connection. Is there any sort restriction known?

Any ideas?

Update - the rest of the code

 (void)updateChatRoomMessages:(NSString *)roomID withBlock:(void (^)(BOOL))completionBlock{ ChatRoomSummary *room = [[DataCollections shared] getChatRoomById:roomID]; Firebase *ref = [[Firebase alloc] initWithUrl:[NSString stringWithFormat:@"%@/chatdata/messages/%@", self.baseURL, roomID]]; [ref observeSingleEventOfType:FEventTypeValue withBlock:^(FDataSnapshot *allMsgs) { dispatch_async(dispatch_get_main_queue(), ^{ [room.messages removeAllObjects]; //clearing the list of messages so that we update it NSDictionary *dict = allMsgs.value; for(NSString *snapshot in [dict allKeys]) { NSDictionary *currentSnapshot = [dict objectForKey:snapshot]; [currentSnapshot setValue:snapshot forKey:@"messageID"]; [[DataEventListener shared] onNewMessage:currentSnapshot forRoom:room preventNotification:YES]; } [Utility notify:NOTIFY_NEW_ROOM]; [self updateBadges:nil]; if (completionBlock) { completionBlock(YES); } }); }]; }
