Invalid method signature supplied (error code 13)

[laMudri]

cmusfm stopped scrobbling for me a few days ago, without any apparent change to my configuration. In trying to diagnose the problem, I've found that cmusfm init always produces:

Checking previous session (user: la_mudri) ...failed.
Fetch new session key [yes/NO]:

I've tried a few times to get a new key, but the new key does not help.

With debugging turned on, I see this from cmusfm init:

Indeed something has changes within scrobbling API, I will check that.

This issue is caused by libcurl bug: curl/curl#5601

Please, upgrade or downgrade libcurl library, anything but libcurl-7.71.0 :).

Yep, can confirm that curl version 7.71.1 is working. 😁
