I am using the OVA. graylog was working fine… when i was logged in , it said i wasnt running the latest version…
so i downloaded the graylog-4.0-repository_latest.deb and ran the update.
wget https://packages.graylog2.org/repo/packages/graylog-4.0-repository_latest.deb
dpkg -i graylog-4.0-repository_latest.deb
apt-get update
apt-get install graylog-server
it finished without error.
Initially when i tried to refresh the page, I got " Graylog is currently not reachable…"
when i researched that, i found that the plugins were not compatible so i removed all non 4.0.1
jar files… now after i restarted GL, i get the front page but it says
“We are experiencing problems connecting to the Graylog server running on http://192.168.1.10:9000/api/ . Please verify that the server is healthy and working correctly.”
9001 is listening… and /etc/init.d/graylog-server status says its running.
here are ERROR lines in the server.log file
