Hi,

After years of working with Kepler, I’ve finally made the move to Havana. I installed Havana on my Ubuntu server, but I can’t get it to work. The server starts completely fine without errors, all ports are open, and the folder structure seems correct. Yet, when I try to access the server IP in my browser, it’s completely unreachable. What could be causing this?

Is it also possible to move the /tools/www folder to a web different web server? Would I need to adjust the paths and recompile the server for that? I’m curious!

Edit: Solved!

Hi Leon.
What is the solution to this problem?
I've tested with the latest Release (Havana-v1.5.1) and source code on Github.
With and without docker. It throws me the same error code in the server console, when I try to enter it via the website. Website unreachable.
Ports open, settings table complete. I feel like I have looked at everything, I just can't understand why. Unless there's something wrong with the latest release. What am I missing? Both the Webserver and Gameserver connect just fine up to the DB. Error acours only when I try too enter the website in the browser. Regardless of full address or only IP.

Error code:
