403 error on /repos

Hello,

I’m trying to access to travis.org web ui since some days that I have not used it and the repositories list remain empty (on the left panel).

The API call to this endpoint https://api.travis-ci.org/repos?repository.active=true&sort_by=current_build:desc&limit=30&include=build.branch,build.commit,build.created_by,build.request,repository.current_build,repository.default_branch,repository.email_subscribed,owner.github_id,owner.installation return a 403 with the following error “installation_missing”

Can you help me to understand the source of this error ? I’have not changed anything

Regards
