Spotify may not be working due to several common reasons including poor internet connection, app bugs or glitches, expired Premium subscription, server issues on Spotify's end, or region restrictions on certain content. Typical fixes include restarting the Spotify app, checking and securing a stable internet connection, updating or reinstalling the app, and verifying the subscription status. Sometimes, clearing cache, freeing up device storage, or checking for Spotify server outages also helps resolve the issue. If the problem persists across devices, it might be linked to the user account or device-specific issues such as firewall settings or software incompatibility.
