What does Spotify Error Code 4 mean?

The short answer

Spotify error code 4 means the app has detected that you have no internet connection, even though you might actually be online.

Why does it happen?

This error shows up when Spotify can’t reach its servers. The message usually says something like “No internet connection detected.” Common causes include:

Your internet is actually down — the simplest explanation is that your Wi-Fi or ethernet connection dropped
Firewall or antivirus blocking Spotify — security software can prevent Spotify from accessing the internet
DNS issues — your computer might be struggling to look up Spotify’s server addresses
VPN or proxy interference — these can sometimes block or reroute traffic in ways Spotify doesn’t handle well
Outdated Spotify app — older versions can have bugs that trigger false connection errors

How to fix it

Try these steps in order:

Check your internet — open a website in your browser to confirm you’re actually online
Restart Spotify — close it completely and reopen it
Allow Spotify through your firewall — in your firewall or antivirus settings, make sure Spotify is on the allowed list
Disable your VPN or proxy — turn it off temporarily and see if Spotify connects
Change your DNS — switch to a public DNS like Google (8.8.8.8) or Cloudflare (1.1.1.1) in your network settings
Update Spotify — make sure you’re running the latest version of the app
Restart your router — unplug it for 30 seconds, then plug it back in

When should you worry?

This error is almost always a network or software issue, not a problem with your Spotify account. However:

If it keeps coming back, your firewall might be repeatedly blocking Spotify after updates — check your security software’s rules
If it only happens on one network, that network may have restrictions that block streaming services
If nothing works, try uninstalling and reinstalling Spotify. Your playlists and saved music are tied to your account, so nothing will be lost
