Login issues
  

The error ''Could not login. Valid authentication credentials were not provided.'' means that you have entered an incorrect password. If you forgot your password you can go to diy.rug.nl to reset it.

New Student?

Once you register for a certain programme, you should receive a student number by mail. If you have not received your student number yet, please contact Information services. More information about Information Services can be found by going to their website https://www.rug.nl/education/information-services/.

If you have received your student number, please activate your student account via diy.rug.nl first. 

Guide:

  1. Check if you are signing in using your student number preceded by an 's'. You can find your student number on your student ID card. An example of a username is "s1234567".
  2. Check if you are able to login to ProgRESS WWW and your student mail. If you are unable to login, continue with step 4.
  3. If you are able to sign in at these sites, please first try to completely close your internet browser, reopen it and type http://nestor.rug.nl in the address bar (so do not go to Nestor using a bookmark or link). Still not working? Then send an e-mail to nestorsupport@rug.nl or call 050 36 38282. Please provide us with the following information:
    - Name
    - Student number
    - The browser
  4. Try changing your password at https://diy.rug.nl
    -
     Choose [Change Password] if your password has expired.
    Choose [Forgotten Password] if you have forgotten your password. Please note: this is only possible if you added an verification question before.
  5. Check if you have paid your tuition fees on time.
  6. Have you been studying at the University of Groningen before, received an alumnus account and did you re-enroll as a student? Then try to login using your old student number and your alumnus password. If this doesn't work, continue with step 7.
  7. If you are unable to solve your problem using the above steps, please contact the CIT Service Desk at 050-36 33232.
