Connected but not scrobbling (Invalid method signature supplied error)

status 28 => CURLE_OPERATION_TIMEDOUT

It seems that you've got some kind of network related issue. Please check if https://ws.audioscrobbler.com/2.0/ (or whichever service you've got defined in the cmusfm.conf file) is reachable from your host.

EDIT: Also, please report this issue as a separate one, because it's not related to "missing required parameter" topic.

Hello again. My scrobbling is stopped for a couple day, now with "Invalid method signature" error.

Could you post full output log? The one you've posted seems to be truncated on the right edge... With the newest master code (release v0.4.0) there suppose to be a string "xxxxxxxxxxxxxxx" somewhere.

[bnsv]

Oh.. You're right, I am sorry. Here it is:

Hello, I've got the same issue - using latest v0.4.0 with debug enabled, I'm unable to scrobble successfully:

Any idea how to fix this? Lastfm's own scrobbler works fine so it's not a connectivity issue.

[catalli]

Also have this error, here's the output when initializing after installing with debug on:

This also showed up when running cmusfm server after reinstalling:

So now I guess it's fallen into the Invalid method signature supplied error?

[arkq]

OK, indeed something is not right. At first I was not able to reproduce this issue, but after full re-initialization with last.fm API I can see it as well. I'll try to fix it as soon as possible.

[arkq]

I think that I've fixed it. This bug has popped up only for cmusfm with debug enabled (with --enable-debug).

[agalloch]

I think that I've fixed it. This bug has popped up only for cmusfm with debug enabled (with --enable-debug).

I've just tested with latest master (8f98d06d7343778591bb663cfef6250546400645) and scrobbling is working once again, thank you sooo much, @Arkq! 😃

For the sake of truth, only for cmusfm with debug enabled is incorrect. I've never used --enable-debug until cmusfm stopped scrobbling some ~2 months~ 1 month ago (circa Jul 12). I could see the ~/.config/cmus/cache file get updated correctly but nothing was sent to Last.fm. It was only then that I've reinstalled with --enable-debug to figure out what went wrong.

Again, for completeness' sake, I can still see <error code="6">Invalid parameters - Your request is missing a required parameter</error> errors when doing cmusfm init:

Grant access to your Last.fm account using the link below, then press ENTER:
  https://www.last.fm/api/auth?api_key=${api_key}&token=${token}

but I guess it does not prevent scrobbling.

[arkq]

For the sake of truth, only for cmusfm with debug enabled is incorrect. I've never used --enable-debug until cmusfm stopped scrobbling some 2 months 1 month ago (circa Jul 12).

That is really strange... Because, I've modified only the code which is wrapped with DEBUG "ifdef"s.

I can still see Invalid parameters - Your request is missing a required parameter errors when doing cmusfm init:

This error message is a correct behavior. By providing incorrect parameters I'm checking whether session key is valid. In case of invalid session key, I've got other error message. And in case of correct session key, I'm not scrobbling anything, because there are invalid parameters :)

[bnsv]

Thank you all for the responds. Actually I was give up for a while on this. Today i give another try to make and reinstalling cmusfm from scratch. Thankfully it is now scrobbling normaly again.
