Firewall Configuration for Scorecerer

The following article is adapted from an article written by Riot Games and is used here with grateful permission.

The following information is mainly for Scorecerer users running Microsoft Windows. However if you are using a Macintosh firewall like Little Snitch, be sure to grant full permission the first time you are prompted.

Many overzealous firewalls can cause problems for Scorecerer users running Windows. They are also the most likely cause of the frustrating "Could not connect to Scorecerer on your Desktop" error message. This article will describe the symptoms, causes and a few solutions to problems caused by firewalls.

Symptoms of a firewall blocking Scorecerer Synchronization:

  • Intermittent synchronization.
    • Receiving the error message: "Could not connect to Scorecerer on your Desktop" after an attempt to synchronize your iPad

    Frequently Asked Questions

    What causes these problems? I didn't have them before.

    This problem can be triggered by a variety of actions:

    Scorecerer Desktop Update:

    When you update to a new version of Scorecerer, firewalls detect that the application has changed and will begin blocking it until explicitly told to allow it again.

    Firewall Update:

    Many firewalls perform auto-updates. Some do not even inform you when they do. This can cause problems if they change the way exceptions work or have mistakenly put Scorecerer Desktop on their blocked application list. Even if you have disabled the firewall, they sometimes continue to block applications.

    Computer System Change:

    Windows Updates, system restore, reformat or reinstalling your firewall can all reset the exceptions you have set on your computer. Performing any of these actions will likely require you to set your exceptions again.

    How vulnerable am I without a firewall?

    Firewalls serve two main purposes. They block incoming and outgoing communications. Blocking INCOMING connections prevents external "hackers" from accessing your computer, usually by manipulating a flaw in Windows or a common application. These attacks are more rare. Most firewalls are built to protect users from themselves. They do this by blocking OUTGOING connections. Outgoing connections are opened by applications running on your system. These are usually harmless, for example Web Browsers, Email applications  and your Instant Messenger all open outgoing connections. This is required for most online applications to function properly. However, sometimes malicious programs such as malware, spyware or viruses open outgoing connections to send data about your system to "home base". This is why most firewalls block outgoing connections by default; they must be explicitly told to allow new applications to use the internet.

    In the case of Scorecerer Desktop, certain incoming connections are required to allow your iPad to connect to it to sync your sheet music.

    Identifying your firewall(s):

    Most users have TWO firewalls installed on their Windows machines and do not even realize it. It is important that when you are experiencing firewall related problems that you make a check list and properly configure each of these firewalls.

    Windows Firewall:

    Windows Firewall is a component of ALL modern day Windows Operating systems. It was introduced in Windows XP Service Pack 2 and has since been included in all versions of Windows. This makes it the most common firewall in use today.

    3rd Party Software Firewall:

    These are consumer firewalls. These tend to be the most aggressive firewalls and cause most of the problems that users experience. There are many free and very good firewalls available today. Many times Anti-Viruses such as Norton Internet Security or McAffee include firewalls with their software. Here is a short list of some of the more common 3rd Party Firewalls.

    • Norton Internet Security
    • McAffee
    • Kapersky
    • ESET NOD32
    • IOBit BitDefender
    • AVG
    • Avira Antivir
    • ZoneAlarm
    • Peerblocker
    • Avast
    • Windows Defender and Microsoft Security Essentials


    Quick Option:

    The quickest and easiest way to solve your problem is simply uninstalling and disabling your firewalls. By doing this, you should understand that it does open you to a very small amount of risk. For more information, please read the above section on "How vulnerable am I without a firewall?". Depending on your situation this may be unwise or impossible. The risk is very small for home users but you may not have this option if you are trying to use Scorecerer on a secure network (office, college dorm, secret government facility).

    1) Disabling Windows Firewall:

    2) Uninstalling Third Party Firewalls

    It is important that you fully uninstall these pieces of software during this step. Often times, the firewalls still block connections even when disabled. This is so important, we will repeat this.

    Often times, the firewalls still block connections even when disabled.

    Slow Option:

    You can alternately choose to add exceptions to each of your firewalls for Scorecerer. This process is difficult and time consuming to troubleshoot because if you miss one little detail the application may still be blocked.

    Generic Instructions:

    Unfortunately, there are many different types and versions of firewalls. It is outside the scope of this article to go into detail about how to configure each one. You may need to contact the make of your firewall to properly configure exceptions for Scorecerer. Many vendors have guides on their website that explain how to setup exceptions for specific applications.

    Generally it requires three steps:

    1. Right-click on the firewall your system tray and access Options or Settings
    2. Find a tab on Exceptions\Allowances\Applications
    3. Add the Scorecerer executable. Be sure to give it "Full Access" or the equivalent setting.
    Again, Riot Games has more comprehensive information on firewall management as well as many other useful links and we encourage you to start there for more information.
    GRAY BAR IN iOS10+
    If you have iOS 10 or later installed on your iPad and see a gray bar covering the menu buttons please do one of the two things:
    1. If you are not using Bluetooth pedal to turn your pages - switch off bluetooth support in Scorecerer preferences
    2. You can also go to "Settings->General->Keyboard" on your iPad and turn off "Shortcuts" option

    If you are having trouble syncing with your iPad, please make sure that
    1. You have iTunes installed OR you have installed the Bonjour service. (Windows users)
      We have heard that completely uninstalling iTunes and then reinstalling it fixes the problem for most users.
    2. Your iPad and your desktop computer are connected to the SAME network!
    3. You have not disabled Bonjour (Windows users)
    4. Your firewall is not blocking Scorecerer (Windows users)
    5. Your iPad has a strong wifi signal from your wifi router, i.e, you are not too far away from your wifi router
