Deploying an aspnetcore 6 web app to Ubuntu 20.04. Here is an article of what I am doing

Apache is now set up to forward requests made to to the ASP.NET Core app running at . It worked before but now its giving me this error.

 dotnet helloapp.dll
Unhandled exception. System.IO.IOException: Failed to bind to address address already in use. ---> Microsoft.AspNetCore.Connections.AddressInUseException: Address already in use ---> System.Net.Sockets.SocketException (98): Address already in use
My service file looks something like

WorkingDirectory=/var/www/helloapp
ExecStart=/usr/local/bin/dotnet /var/www/helloapp/helloapp.dll

RestartSec=10
KillSignal=SIGINT
SyslogIdentifier=dotnet-example
User=apache
Environment=ASPNETCORE_ENVIRONMENT=Production
[Install]
WantedBy=multi-user.target

and config like

<VirtualHost *:80> ProxyPreserveHost On ProxyPass / ProxyPassReverse / ServerName ServerAlias *.example.com ErrorLog ${APACHE_LOG_DIR}helloapp-error.log CustomLog ${APACHE_LOG_DIR}helloapp-access.log common
