Graylog sidecar v4.0.5

Hello all,

after upgrade graylog from version 3.x to v4.0.5 i’ve encountered this issue on graylog sidecar:

level=error msg="[UpdateRegistration] Failed to report collector status to server: Put \"http://server:9000/api/sidecars/d99718d7-167b-45d4-9d54-56194d8d107a\": dial tcp ipaddress:9000: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond."

The server side configuration is a Windows Event log sending and with previous version all work correctly.
I try to rebuild the configuration step-by-step with official documentation but probably i’m doing somethings wrong.

any suggestions?


Is that the only error you are seeing in all the client side logs? For windows you find them here by default: C:\Program Files\Graylog\sidecar\logs What do your (genericized) windows sidecar configuration look like? Confirm all the paths it has to actual folders/files. Post more information allows us to see a bigger picture.

solved, the problem was on my firewall sorry for posting.


Post up the solution in case others run into the same issue and are searching the forum…
