    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.

    Reset "Acknowledge" when build is green again

    matthias · 2 · Last reply by catlight

    When you have acknowledged a failing build (git branch) and the build turns green again it is still marked as acknowledged. You can right-click the green build and remove the "acknowledged check".

    The "acknowledged status" should be resetted as soon as build turns green.

    Not sure about the current side-effects but I would guess that you would not notice when build turns red again since it is still marked as acknowledged. Unfortunately this is not too easy to reproduce.


    BR, Matthias

    Cannot start the app in Windows 10

    Dean OCallaghan · 2 · Last reply by Dean OCallaghan

    I have just installed CatLight 2.10.3 on a Windows 10 machine, but it won't run. The gears spin for a minute or two, and then the screen says "cannot start the app".

    I tried installing the CRT but the installer said that it wasn't applicable to my version of windows.

    I have attached the log files.

    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.

    Adding a VSTS connection fails

    hrant · 2 · Last reply by catlight

    When I add a VSTS connection, I'm properly prompted to Accept or Deny

    I click on Accept, and I get redirected to localhost with an AccessToken in the URI, however the local server reports the following.

    TFS2015: Offline - Sequence contains no elements

    BC · 3 · Last reply by catlight

    Hi Tim,

    Since version 2.7.0 I cannot connect to our local TFS on prem anymore.

    I keep seeing this error message:


    Sequence contains no elements


    Sometimes a restart of the app fixes it temporarily. But then all of a sudden, boom, same error again.

    I was hoping this bug had been fixed in v 2.7.1 but unfortunately it isn't.


    Hope you can fix this since we really rely on Catlight nowadays :) (And we're paid customers... ;)

    Duplicate projects in Jenkins appear in the interface

    Alex · 6 · Last reply by Alex

    It appears that i have the Master project in Jenkins twice, one that states that the build is broken and needs investigating, the other one states that no build has ever started on that project. This is regarding Jenkins.


    I have attached a picture to see exactly what is happening.

    Catlight does not start when Windows starts

    Keith · 1 · Last reply by Keith

    This has been happening since I started using Catlight a year ago. Catlight installs a shortcut to my Start Menu\Programs\Startup folder but for some reason it never launches during startup. I always have to manually start Catlight. The shortcut is valid because it does launch Catlight when I double click it so not sure why it does not run during Windows startup.

    I'm currently using v2.5.10 on Windows 10. The startup shortcut is installed in C:\Users\{my username}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup. 

    Shortcut's target = C:\Users\{my username}\AppData\Local\CatLight\Update.exe --processStart "CatLight.exe" -a "--on-startup"

    Shortcut's "start in" location = C:\Users\{my username}\AppData\Local\CatLight\app-2.5.10

    I don't see any travis builds.

    Lukas Malkmus · 3 · Last reply by Dylan Green


    I connected CatLight to Travis-CI Pro, but I don't see any builds. Maybe it's because I have a student account?


    I hope we can fix that :)

    Problems with Work Item tracking

    Graham Smith · 1 · Last reply by catlight

    I set up my Catlight to do work item tracking - some time ago (possibly in a beta build)

    I've just tried to add another query to my work item tracking, and the context menu where you can choose "Show All" or other options is not rendering right.  It is clipped off so that the menu/popup is completely unusable.

    In the below screenshot, "Build Failures" was set up some time ago (i don't remember when or how) and has a blue cat icon.

    The "Failed Testing" query is newly created, has a empty cat icon, and the context menu is

    Builds order for Team City sub-projects

    Marcin Daczkowski · 1 · Last reply by catlight

    Not sure if this happens for other CI servers too, but for Team City builds are organized in alphabetical manner. As I have some projects with sub-projects, I end up with related builds quite distant. I can work around this by prefixing Team City builds for sub projects, so they have common prefix, that should keep them together, though it seems to me this could be automated for better/easier organization.

    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.
