scanner error without network connection

[DerMatze87]

If I use my CasparCG Server 2.3.0 without an network connection, the scanner node process throws errors and I couldn't use cls an other scanner function on server. How can I solve this problem?

Hi there. Could you please add the full log? I cannot see anything there relating to what is causing the issue from inside the scanner itself.

Here is the full output from scanner.

Right, so afaik with nodejs, no network interface = not able to use the network stack. So what you will need to do, is to setup a loopback adaptor so that node can bind to a 'network interface' - see here for details: https://preparingwindows.com/microsoft-loopback-adapter-windows-10/

Also, see the changes I made in my IPv6 fix PR (that needs to be merged in still), apply those to your source code, and rebuild. Otherwise you may find it tries to bind to an IPv6 port in the loopback.

Thanks, the solution with loopback adaptor works fine.
