Hello to whom it may concern,
I am in charge up upgrading our current install of graylog 2.5 to 3.1. I have the new server up and running ,and graylog is functional, but I am failing to import our custom configuration to our new install.
I get the following error: Installing content pack failed with status: Error cannot POST http://[IP Address:9000]/api/system/content_packs/71e8e80d-a69b.
I know the database works because I made some changes individually, and they saved without a problem. I was also able to install the default content packs without any issue.
