Setting “Enable TLS for NodeJS Server” to NO in Advanced Settings got rid of that message, so that’s a step in the right direction. I think it lends some credence to the idea that this is really a certificate issue.
I also still don’t know how to configure XMPP. All the old threads mention paying for it but I don’t think it’s a paid module anymore. Or at the very least I can’t seem to find it in the store anywhere.
