I believe I am correctly running a public Electrum node at btc.mustyoshi.com:50001

You server doesn't seem to be connected on IRC... So no, you're not correctly running a public Electrum node

How do I fix that? I thought I had the config file setup right.
EDIT: So apparently report_host can't be the same as host.

host is the IP of the server
report_host is the FQDN of the server
