Using a Sparrow wallet on the Start9 I attempted to connect Electrum Private Server using the local IP address of the server on my LAN in the URL box and Port 50001 with no SSL, no Proxy. TEST CONNECTION returns “connection refused”. Electrs and Bitcoin Knots both show all good in SERVICES. Trying the same thing on the Sparrow wallet on a MacBook on my LAN gives the same result.
If you are using the Sparrow wallet service on your server, you don’t have to do anything except select “Electrs” in the service configuration (in StartOS, not sparrow) and it will work.
If you want to connect to electrs from Sparrow on a different PC/Mac, follow the guide here: electrs-startos/docs/integrations/sparrow/guide.md at master · Start9Labs/electrs-startos · GitHub
note that currently you can only connect this way over tor (using the .onion url).
