[SOLVED] Deflector issue on graylog fresh install

Hi all,
i’ve installed graylog on a centos 7, all installations have succeded but at the first logon i found this error on system state

how i can solve this? i’ve found some post in the community but none of this reflect my scenario.
many thanks

But this FAQ entry is about this issue:


You might also want to check your elasticsearch version - only 5.x (and 2.x) is supported with the current Graylog release.

my fault … i’ve installed a 6.x version of elastic, with 5.x all work fine, thank you.
