when I go to Alerts -> Notifications I get the following error:
Could not retrieve available alert notifications
Fetching available alert notification types failed with status: cannot GET http://10.150.150.5:9000/api/alerts/callbacks/types (500)
Then I go to the REST API browser to the function “/alerts/callback/types” and get back this Response:
“message”: “Duplicate key siser01”
What can I do to solve this?
Graylog is latest (2.4.4), everything else works fine.
Thanks in advance,
