Public repository triggers Travis builds while private doesn't


I’m currently working on a project and I’m using Travis for CI.
Builds don’t trigger unless repository is made public.
Private and public have the exact same content but for some reason builds only trigger on the public one.
I must be doing something wrong or missing something as some of my classmates told me they managed to get builds running with a private repository

Here is the link to my travis builds :


It returns “Could not authorize build request”
Apparently it would be about subscriptions or because I ran out of free trials
The problem is I haven’t built that much so I seems strange to me

Do you have any clue of what could have caused this ?

Check to see if you have a subscription and/or credits.
