grab-site not displaying any content on Port 29000, but installed and running

[DominicBilke]

Hello,

I have installed grab-site on my IONOS-Server and it's running when I call ./gs-server

But it's not diplaying any content when I open Port 29000 from the web.
There's site unavailable. I opened the port on the server, but there's no content.
There's no error message.

I have created following service:

[Unit]
Description=GrabSite

[Service]
WorkingDirectory=/var/www/vhosts/bilke-projects.com/grab-site/
ExecStart=/var/www/vhosts/bilke-projects.com/grab-site/gs-server
Environment="GRAB_SITE_INTERFACE=82.165.222.1"
Restart=always
RestartSec=5
TimeoutSec=10

[Install]
WantedBy=multi-user.target

If you have any suggestions, please answer.

Greetings,
Dominic Bilke

Did you check the firewall settings in the IONOS control panel? I think they might block ports by default

The firewall ist open for Port 29000.

I checked the service-status, it's running with gs-server.

When I load the IP and the Port (http://82.165.222.1:29000/) it displays: Site is not available.

Do you have any other suggestions?
