Just installed / updated to Graylog v2.4.5 on a multi-node setup. Now this API-checks is empty:
curl -u user:SECRET -H 'Accept: application/json' -X GET 'http://10.11.12.13:9000/api/cluster?pretty=true'This check used to work on v2.4.4 and used for monitoring.
Has anything changed in the API and if so is there anyone here to enlighten me? TIA!
No, there’s haven’t been any changes in this area, see http://docs.graylog.org/en/2.4/pages/changelog.html#graylog-2-4-5 for the complete change log and https://github.com/Graylog2/graylog2-server/compare/2.4.4...2.4.5 for a diff on GitHub.
Check the logs of your Graylog nodes.

Thanks Jochen. Using a token for authentication does work, so this is probably a PEBKAC on my side. The token was setup more recently than our checks were updated.
So once a auth-token has been setup, user:password will not work in my opinion.
As a general hint, adding -i (informational) or -v (verbose) to a cURL command will often help identifying the cause of a failed request. 
Nope, authentication with username and password should still work, even if access tokens exist for the user.
