Plex can't see the server

[jpsaf]

My TerraMaster:
F4-420 NAS has
TOS Version 5.1.41
BIOS 5.6.5
I installed PLEX Media Server from PLEX source manually this file c
Installtion worked fine. I open the Plex Icon on Terramaster desktop, which opens a new tab with the PLEX.
When I try to access "Your Media", not my server appears, only a button "Get Plex Media Server".
This is exaclty the location where I downloaded PlexMediaServer-1.32.5.7349-8f4248874-x86_64_TOS5.tpk
It is like the server with my files is not found and it feels a little like a death end...

During the installation process, I switched the language from French to English. Everything went well after that.

Please check whether you have given the directory permissions to the Plex-related user group "media"
