I've set up a stellar.toml for my federation server and implemented the federation API endpoint as documented here https://www.stellar.org/developers/guides/concepts/federation.html. The only purpose of the server is to translate vanity addresses to public keys + text memos.
When I try to send XLM to user*myproduct.com however, Stellar account viewer tells me: "Stellar address cannot be found or is invalid."
I'm fairly confident that the stellar.toml file and the federation endpoint therein are implemented correctly and publicly accessible.
How can I debug this? What's the best way to figure out what is going wrong?
