Hello! I can not go through the web login and password admin-Invalid credentials. Tried to change the password through graylog-ctl, but graylog-ctl: command not found . What to do? ---

Looks like alpha version of VM does not have _graylog-ctl_ utility. Also the password is not _admin_ for sure. I would suggest to edit _/etc/graylog/server/server.conf_ and replace `root_password_sha2 = 666881d6a203c23a94390e39f9a369773c74e837af03bbeb5b40c8dd5c0c5a4e` with `8c6976e5b5410415bde908bd4dee15dfb167a9c873fc4bb8a81f6f2ab448a918` Then restart graylog service or reboot VM. Now you could log on with admin/admin credentials ---
