Hi @amatala,
The old Audioscrobbler API is deprecated, and I suspect the client and version were never implemented for it (it was only added as a suggested field in the ListenBrainz API maybe 5 years ago)
Judging from the code, I don’t see any parsing of v or c parameters, so I think thye are just ignored.
Is LMS Logitech media server? If so, there might be a better option to submit to ListenBrainz: Lyrion now supports ListenBrainz scrobbling - #2 by Paul_Webster
In any case, I’m happy to help you figure out a way to use the regular API, if possible, that works with your setup.
Let me know.
