I've got the XTTS server running and can see the voices and it works fine when using SillyTavern on my local computer, but when I move to my phone, I get a message from SillyTavern stating "TTS Provider failed to return voice ids"

I've ensured the --listen argument is present and working and that my server is listening on all interfaces. I have also verified this behavior follows to other systems as well. It only seems to work on the local machine. I've tried turning streaming mode on and off, changing ports, rebooting each tested machine, and have restarted the server several times.

When selecting "Available Voices" I get "could not load voices list. Check your API key."
