Stopping via systemd leads to kill after timeout

[nblock]

Bug description

Invoking: systemctl restart headscale hangs until systemd hits the stop timeout. Afterwards headscale is killed.

To Reproduce

Systemd service file:

[Unit]
Description=Headscale (version: 0.16.0-beta4)
[Service]
Type=simple
User=headscale
Group=headscale
RuntimeDirectory=headscale
Environment=GIN_MODE=release
ExecStart=/usr/local/bin/headscale serve
ExecReload=/usr/bin/kill -HUP $MAINPID
Restart=always
RestartSec=5
ReadWritePaths=/var/lib/headscale/.headscale
ReadWritePaths=/var/run/headscale

[Install]
WantedBy=multi-user.target
