I’m quite sure it’s not the same problem, since I can’t get to the GUI even when I’m using the IP…
It’s a very simple installation, everything default, with no HTTPS - just OVA from Graylog website updated to the latest version and then upgraded to the latest 4.0 version.
Howdy @CatchyNick. I just spun up the ova on 3.3.9-1 and upgraded to latest. I ran into the issue that @tmacgbay mentioned, enabled cors, and was able to log in. Did you ever get any info from your browsers devtools console?
