I have just uploaded a new version (2023.0.9) - see announcements section for link.
I have fixed a couple of the issues you were having and put in further error traps to further isolate the issues.
I have tested stereo pairs and was also getting the UPNP 500 error. However if I delete the slave device (in Indigo) and only define the master of the pair to Indigo then it appears to work OK for me. Scanning back over this Sonos forum and searching for "Stereo pair", various posts suggest only defining the master | controlling speaker of the pair.
I accept this may have worked before but we need to bear in mind that the SoCo version is now ten versions ahead of what is used in the Python 2 version of the plugin.
Let me know if this will work for you. If not, please let me know what your requirement is so that I cna investigate how to best manage this. Thanks.
