Scrobble Last.fm from Deezer not working

My last.fm account is tied to the account deezer, but recently the tracks began to scrobble in a few hours, the listening time does not match, the songs go one by one with an interval of about a minute (with a duration of 3-4-5-6-7 tracks minutes). The problem is present in both the mobile application and the desktop.

Deezer was not updated (The latest available version is used everywhere). Please, fix it!

Sorry. I duplicated this error in the appropriate topic: https://en.deezercommunity.com/troubleshooting-and-tips-4/scrobble-last-fm-697

I think my topic can be closed?

@eames thanks for linking the corresponding discussion in the Last.fm forum! I'm assuming Last.fm is looking into this now as well since it was reported there.
As @bluezzbastardzz explained, the scrobbler browser extension should still work - can you use this workaround?

I'm using Deezer premium and have it chained with my last.fm account, and there is a bug that seems to be happening at totally random times: there are songs that get scrobbled at least 10 times on last.fm. I've also use Musicbee and youtube, and this never happens, so I'm totally convinced this is a Deezer thing. There are other pages around the Internet with info regarding this problem with other users, read this one: https://www.reddit.com/r/deezer/comments/8eh759/when_will_deezer_fix_the_multiple_lastfm/

Thanks for reporting this problem. Is this related to the Android app? Normally last.fm integration is only on Deezer website.

Hi @Jean-Baptite Vincey, I use deezer on web and on mobile app. I'm not using any third party scrobbling app. I connected my deezer and last.fm accounts using the info ion this link (in spanish https://support.deezer.com/hc/es/articles/201331201-Conectarse-a-Last-fm) from then on (about a year ago) all my played tracks on deezer are scrobbled to last.fm, some of the randomly getting between 5 to 10 scrobbles per song played (most of the times with two songs in a row, meaning 20 scrobbles, 10 per song, and 18 duplicates). I'm not sure if this happens only with my song on mobile, but now that you mention it, it might be so as I don't recall having this issue with my web playing music.

I confirm I have this issue too - on the desktop beta app (on Windows) v0.9.1. Started to misbehave perhaps two weeks ago or so. Will be glad to provide more information about the issue as needed, on that app or the mobile Android beta.

Hello! I have a problem with last fm synchronization recently. Seems like Deezer app multiplies the number of plays of the song and I have to delete them all the time.

Hi there, please see @eames above 😉

It's unlikely that Last.fm will fix anything, as the internal Deezer implementation does not seem to be working correctly anymore. While trying to connect to my Last.fm profile for authentication of the internal Deezer scrobbling option, I got this error message on the first try:

"Invalid API key. If you are a third party developer see our authentication how-to to find out more."

So it is possible that your developers may have to check if their Last.fm API key is still valid, if this error message is true. Or maybe they changed something else recently which causes the problems now.
