Hello all!
I'm new in Ragnarok and of course new as well in this forum.
Just trying to get a local private server up and running, but having some doubts and issues regarding server and client-side configuration. Also read some tutorials and looked around to see if someone got this kind of issue and if it was resolved, but didn't find ans effective answer. So if this post is in a wrong place, or, if there's an answer for this kind of problem, please guide me to find the correct answer.
1st things 1st, my server environment is
Virtual machine using Ubuntu 20.04 for OS (4Gb RAM, 128Gb HDD, 2 processors).
Cloned rAthena from git clone https://github.com/rathena/rathena.git ~/rAthena and got all updates (git pull).
Got installed Apache2, php7.4, MySQL Server, phpMyAdmin, as well as all necessary libs and dependencies to compile and create login-server, char-server and map-server.
Using a clean kRO installation and 2018-06-20eRagexeRE_patched (also had edited grf files inserting virtual IP address assigned to my linux server).
Have no firewall rules blocking/denying traffic for destination server ip address and ports.
Error Messages/screenshots
Both client-side error (Failed to connect server) and server-side message (Closed connection from...) are attached to the post.
NOTE: If there's an updated tutorial teaching how to get things configured and running, for a newbie like me, please let me know.
