PhiServer on Ubuntu as systemd service

[aiscy]

Hello! I'm trying to setup your server as systemd service but got some trouble.
When I run it manually it works well

aiscy@ogryzok2:~$ mono /home/aiscy/PhiServer/PhiServer.exe
WARNING: The runtime version supported by this application is unavailable.
Using default runtime: v4.0.30319
Launching server for 0.0.0.0 on port 16180

But if I run as service, I get this message:

Loaded: loaded (/etc/systemd/system/phiserver.service; enabled; vendor preset: enabled)

Here's my service script:

[Unit]
Description=Rimworld Phi server
[Service]
ExecStart=/usr/bin/mono /home/aiscy/PhiServer/PhiServer.exe
WorkingDirectory=/home/aiscy/PhiServer
Type=simple
[Install]
WantedBy=multi-user.target

Could you please tell me what am I doing wrong?

Fixed?

I'm using screen as workaround ;(
