Hey there,
TL;TR:
My problem is similar to: https://community.atlassian.com/t5/Bitbucket-questions/Jenkins-could-NOT-discover-Repositories/qaq-p/1540027
Although,
I tried both using user:password and/or user:app-password and it didn't change the results.

Already checked:
- the credentials,
- user permissions (granted admin),
- job configurations (nothing changed),
- logs for errors (nothing found),
- connection between bitbucket-cloud and jenkins (working fine)
I validated the 1,2,3 and 5 by creating a job of type "pipeline" and loading it from a pipeline-library we have on bitbucket, it successful retrieve from bitbucket as do everything it should.
The only problem is that the plugin suddently stopped from "reading" the bitbucket team info and importing the repos to the jenkins platform.
Some info about the environment:
- I'm using bitbucket plugin at version 1.1.29
- Jenkins platform is running at version 2.777.4 (also tried 2.289.2 and 2.303.1)
