Describe the Bug

Given that the app has my api key and secret, it should be able to login automatically without an "Auth Interaction Required" error.

Here's my settings that I have right now for last.fm:

{
    "name": "angel_lastfm",
    "enable": true,
    "configureAs": "client",
    "data": {
        "apiKey": "...",
        "secret": "...",
        "redirectUri": "http://192.168.50.60:9078/lastfm/callback"
    }
}

I also made sure to have the same redirect callback url when creating the api in last.fm itself.

Here's my jellyfin config, although I don't think jellyfin causes any issues here...:

{
    "name": "angel_jellyfin",
    "enable": true,
    "clients": [
        "angel_lastfm"
    ],
    "data": {
        "url": "...",
        "user": "angelolz",
        "apiKey": "..."
    },
    "options": {
        "logPayload": true,
        "logFilterFailure": "warn"
    }
}

Error: API call failed due -> operation failed <- after max retries hit 2
caused by: Error: Operation failed - Most likely the backend service failed. Please try again.

operation failed is a specific error code returned by the last.fm api. Your auth is likely fine and multi-scrobbler was able to communicate with last.fm but they were likely experiencing an error on their side.

Try restarting MS now, hopefully they've fixed the problem.

@angelolz did you try restarting multi-scrobbler?

[angelolz]

Sorry for the late response, but I have restarted multi-scrobbler. I have also tried to make a new app and use the API key/secret of that and still shows the same errors.
