Login failed issue

[knedl1k]

I am using Arch Linux with current Kernel.

After following the instructions mentioned in the README

• downloading all dependencies, changing to librespot = "0.4.2" in Cargo.toml & building the app
• creating a new application
• changing username, password, client_id, client_secret to corresponding values in settings.json

and after trying to download random album from Spotify, the output is:

Settings successfully loaded.
Continuing with spotify account: <username>.
Login failed, possibly due to invalid credentials or settings: Authentication Error

My actual username is replaced in this issue with <username> for privacy reasons. I have tried changing the password various times, or reinstalling the app, but without success.

I would be glad if someone could advise me where the problem might be, or how to try to solve the problem.
