Can't find server files

A while back, I made a server with Oracle Cloud Infrastructure. I left the server alone for a while and am trying to return and update my Minecraft world. I can log into the server and the world is running 1.20.1 of Minecraft. (This is verified by checking features.) However, when I use Putty or Filezilla to access the server, I can't find this version or the current state of the world. The files shown are version 1.19.3 and the world is in the same state that it was over a year ago with the files dated April 2023. I am connecting to the same public IP address when running Minecraft and when accessing the files through Putty and Filezilla.

I previously had access to my world through Pterodactyl, but something happened, and that stopped working. I would like to get access to the actual current server files and update things. Ideally, I would like to setup Pterodactyl once again, but I would settle for being able to find, download, and edit the current server files.

I'm technically savvy, but I'm a noob to the world of servers, etc. I feel like there is something simple and obvious that I may be missing, but I can't understand why the files I access through file management is different from the files I must be accessing through a Minecraft instance.
