regarding -> [2019-09-28 09:42:40.153 +00:00] [ERR] HTTP request failed with message: "{\"error\":13,\"message\":\"Invalid method signature supplied\"}" Some notes at https://www.last.fm/api/authspec#8 regarding the auth API spec . This point seems to stand out and is not adhered to Ensure your parameters are utf8 encoded. it could be a one-line fix.

After rebuilding, it seems to scrobble ok. Will test some more and submit a new build/version
