Common Problems

    I'm using VSTS and it works. After a couple of hours, it stops working with 'Configuration Needed'

    Configuration Needed

    Authentication needed. Error message: TF400813%3a+Resource+not+available+for+anonymous+access.+Client+authentication+required.

    When I click the Configure link after it, it reconnects.

    This is not desirable if I'm expecting notifications and can't tell that it is down unless I go to the dashboard.

    Jenkins connection problems (error 500)

    catlight · 1 · Last reply by Harman

    If your CatLight cannot connect to Jenkins and shows 500 server error, please check your server version. It is displayed at the bottom of every Jenkins page.

    We support Jenkins versions starting from 1.644 (released in early 2016) and 2.x 

    Older version of Jenkins have bugs in the API that can result in server errors. If you have old version, consider upgrading your server.

    TFS XAML builds can show old status and notifications

    catlight · 2 · Last reply by catlight

    We have found a problem with TFS API - it does not sort XAML builds properly. As a result, occasionally it will not provide a latest build information, but return older builds instead. We have submitted bug report to Microsoft and are looking for workarounds. 


    This applies only to XAML builds. Other types of builds and other build systems should work fine.

    "I will investigate" has sync problems

    Recently we have seen problems with the "I will investigate" functionality. It has mainly 2 issues:

    1. A person can "hang" as "investigating" on other persons' Catlight instance, while the person in question has a Catlight instance that says he/she is not currently investigating anything. - this one is critical, because we have errors that aren't looked into for a long while, until somebody asks the person why he/she hasn't fixed the error yet...!
    2. "Investigating" isn't cleared after a green build, but must instead manually be cleared. This also leads to wrong behavior, because if a build breaks, a person investigates,

    Clicking "Build Now" generates a "Error: Request failed with status code 500"

    Harman · 3 · Last reply by catlight

    Currently have CatLight connected to Jenkins version 2.46.2. CatLight will give notification when builds start/finish but will give the above error when I try to start a build through CatLight. Proper credentials are provided for Jenkins login.

    TFS2015: Response status code does not indicate success:500 (Internal Server Error)

    Jason · 3 · Last reply by catlight

    I've upgraded to the latest build (v 2.0.14 Beta), and tried to change the builds I monitor, after doing this I started seeing the message: Response status code does not indicate success:500 (Internal Server Error)

    Looking at fiddler most of the projects being polled are fine except 1 which is returning the 500. However I am not subscribing to any builds associated with that project so I wouldn't expect this one failing to bring down the rest.

    The menu on OS X don't follow Apple's Human Interface Guidelines

    Asbjørn Ulsberg · 0 · Posted

    In the OS X app, the menu items look like this:

    • Catlight
      • Open Dashboard
      • Exit
    • Edit
      • Add Connection to TFS or VSTS
      • Add Connection to AppVeyor

      • Emoji & Symbols
    • Help and Feedback
      • View Help
      • Provide a Suggestion
      • Report a Problem
      • About

    This is not according to Apple's Human Interface Guidelines. Instead, I suggest the menus should look more like this:

      • About Catlight
      • Preferences...
      • Add Connection...
      • Quit Catlight
    • Help

    Teamcity authentication issue if using NTLM

    Daniel Sack · 1 · Last reply by catlight


    At the moment, CatLight cannot connect to teamcity if only NTLM is used. GitExtensions is having the same Issue currently. To workaround this issue it's possible to get an authentication cookie when ntlmlogin.html page is browsed. This authentication cookie can than be passed for further rest calls.

    a powsershell sample can be found in the answer from mclayton on

    I had Catlight running initially and liked it a lot. But after installing some prerequisites for other software (including .NET 3.5) on my machine, I've started getting this error when running it:

     It keeps trying the same thing for a minute or two before giving up.

    I've tried repairing some of the installed programs like .NET 4.5.2 and MVC 4 but to no avail. I also cleared everything in %APPDATA%\Catlight and reinstalled Catlight.


    Any insight would be helpful, so I don't have to go looking for another program to keep me notified of my builds :)

    Gears Spin Indefinitely upon first setup

    J · 14 · Last reply by Jason Haffey

    I'm the DevOps guy and for me CatLight installed perfectly fine. But I asked my developers to install CatLight so they can see very quickly if/when their checkins break builds. For many of them upon opening setup.exe, the dashboard shows gears spinning indefinitely.

    Secondary monitor problems

    Arpad · 3 · Last reply by catlight

    Then I open the Dashboard on my secondary monitor and then log onto that computer via RDP (with only one monitor) the dashboard is somehow hidden. Even after I restart CatLight it memorizes that it was on the other monitor and can't get it into view.

    Today CatLight prompted me to re-init my TFS connection which is for a Visual Studio Online account. When I click Save on the TFS connection settings screen, it opens a page in my browser to authorize CatLight. When I click Accept, I get this message (base URL obfuscated on purpose):

    Jenkins GitHub Organization Folders aren't showing builds

    Christian Höltje · 4 · Last reply by catlight

    I use the [GitHub Organization Folders]( connected to a GitHub Enterprise along with the new Pipeline goodness to do builds.

    However, catlight only shows the top-level folders.  I expected it to show the nested builds underneath.

    Here is an example:

    • OrgOne
      • Uno
        • production
      • Eins
        • master
        • v2.x
        • experimental
      • Singular
        • master
    • OrgTwo
      • Duo
        • master
      • Zwei
        • master
      • Doubled
        • master
        • PR-10
        • PR-11
        • PR-12

    Only the leaf nodes are actual buildable jobs. Everything else is a folder.  The Jobs that have names like `PR-XX` are github pull requests are expected to be transient (depending on the life of the pull request) do not show that

    Invalid URI: The Uri scheme is too long.

    Jan Prause · 3 · Last reply by catlight


    since today I get the following error message "Invalid URI: The Uri scheme is too long.". And tried a little bit and found out that is because I choosed too many build definitions. If I deselect some of the definitions, everything works fine.

    I get a windows notification that my build has started. I click the dashboard and it still doesn't have the update. Even after a couple minutes the dashboard still does not update the information. My polling interval is set to 60 seconds.

    Now I can only mark one at a time. Once I select "I will investigate" on the second build, the first one is unselected automatically.
