IPv6 on Windows 10 breaks IPv4

I run a few different apps on a Windows 10 PC at home which are accessible from the Internet using Dynamic DNS and I've been reconfiguring them all to support both IPv6 and IPv4 and got most of them working fine.

Calibre is the last one I need to do, but I am having problems making it work with both IPv4 and IPv6 at the same time.

If I change "the interface on which to listen for connections" setting in the "Sharing over the Net -> advanced" settings to "::", then it listens happily on IPv6 and is fully accessible both from my own network and externally using IPv6. However, it doesn't seem to be listening on IPv4 and access from any non-IPv6 enabled client doesn't work.

If I revert the setting back to None, then IPv4 works, but IPv6 doesn't.

I'm running 3.37.0.

Has anyone else got this working or got any suggestions of how to fix it?

Thanks
Paul
