Article Overview


HuskyCT is the official application by which UConn students access their courses online. It is a browser-based application used by the University of Connecticut to offer online courses, materials, and exams. Some browsers do not work properly with HuskyCT in their default configuration because the website depends on pop-ups.

HuskyCT can be accessed by typing either or into your browser.

  • If issues logging in to HuskyCT are reported, try logging in via the Guest Login (beneath the NetID login button).

  • If you are unable to log in to Guest, then the problem lies with HuskyCT.

Required Add-Ons for HuskyCT

Reading PDFs

In order to view and download PDF’s off of HuskyCT, the computer needs to have some form of PDF reader installed. The most common PDF reader available is Adobe Acrobat Reader. You can also use Foxit as an alternative to Adobe.

  • Adobe Acrobat Reader is a free program for viewing, printing, and commenting on PDF documents. It enables the user to open and interact with all types of PDF content, including forms and multimedia.
  • Foxit Reader is a PDF viewer that allows you to open, view, and print any PDF file. Unlike other readers, Foxit Reader includes easy-to-use collaboration features like the ability to add annotations, fill out forms, and share information with social networks.

Reading, Editing and Creating Microsoft Office Documents

In order to view and download Microsoft Office documents, the user is required to have Microsoft Office Suite (even if it is just the basic one), which can be accessed by all students for free on through Office 365.
The two most common file formats that are encountered involving MS office are .doc or .docx (opened by Word) and .pptx or .ppt (opened by PowerPoint). Other free word processing software does exist, but these programs may be unable to open these specific formats.

Playing Movies

Adobe Flash

Adobe Flash is a multimedia platform used to add animation, video, and interactivity to web pages. Flash Video, which was first introduced with Flash version 6, has been a popular choice for websites due to the large installed user base and programmability of Flash. Depending on what format the professor uploads, the HuskyCT platform may require Flash to be installed in order for students to watch movies.

Quick Time

QuickTime, and Apple product, is capable of handling various formats of digital video, picture, sound, panoramic images, and interactivity. If a professor uploads the media content as QuickTime, this program will be required for the student to view the file.

HuskyCT requires the use of pop-ups for some of its functionality. When viewing grades or opening a discussion post, a pop-up window may appear. If a pop-up blocker is turned on, these windows will be blocked and the user will be unable to access the desired information.

Blank Boxes when Using Firefox Browser v.81

You may encounter only blank boxes instead of your courses or course information when using Firefox v.81.  This seems to be a Firefox bug; the only identified fix for this at present is to use a different web browser program.

Issues with Finding Classes 

If you are unable to locate a class, or a class is missing from HuskyCT, try the following:

  • Access HuskyCT via or, and don't use an old bookmark or search results.
    • The site can change, so any old bookmarks will bring up an error message (i.e. “Website is unavailable”, “Site is no longer here”, etc)
  • Make sure the My HuskyCT Class box is not collapsed. There is a small arrow to the left of the box, and clicking it collapses or expands your class lists.
  • If none of the above resolves the issue:
    • Contact the professor and verify you are on the professor’s roster.
    • Contact the professor to confirm that the professor uses HuskyCT, as not all instructors use HuskyCT. . 
  • If you are still having issues, contact the ITS Help Center to provide a technician with the Course Department, Course Number, Course Name, Section #, and Professor.

Classes will appear in HuskyCT to students on the FIRST DAY of classes at beginning at midnight at the beginning of that day.

If a student joins a class late, it can take up to 24 hours for the course to appear in HuskyCT.
