Lines that do matter
[PlayNHost] The ARK server process stopped on its own; restarting the server.: the game ended by itself and the panel restarted it. See ARK: Survival Ascended server problems and fixes.[PlayNHost] The default admin password is never used: this server's is in the file .pnh-ark-admin (Files). Set your own under Settings.: not an error. It shows only when Admin Password holds the shared placeholder word instead of a password of its own, so the server used a random one from that file. Type a password of your own in Admin Password and restart: How to become admin on your ARK: Survival Ascended server.
