I have been using Docker Graylog for 2 months. I started to receive the “Invalid credentials, please verify them and retry.” error since 2019-05-08 03:28 in web interface login. Also I can login with “admin” user, I see that have lost all defined configuration. (streams, content packages, alert integration, etc.) On the other hand, I checked the Mongo/graylog db, I saw that there are no user, stream, etc. definitions. How is it possible to lose this information?
