Sometimes Spotify users aren’t able to log in to their Spotify account and see an error message saying “A firewall may be blocking Spotify. Please update your firewall to allow Spotify. Additionally you could try changing the currently used proxy settings. (Error code: 30)”. The error looks like this:
We’ve been receiving reports that users still can’t log in even after disabling the firewall or adjusting the proxy settings, as the error message suggests. The error comes up on the desktop app while users can successfully log in on mobile devices.
After investigating further with our tech team we found the issue could be caused by individual network set-ups. However, here are some troubleshooting steps that may help you fix the issue:
Perform a clean reinstall of the app following these steps.
Check your firewall and antivirus software or apps to make sure Spotify is whitelisted or set as an exception.
Remove the entries from your Windows hosts file - make sure you remove all the entries, not just the Spotify ones.
Uninstall any ad-blocker apps.
Run Windows in Safe Mode with Networking. If the app works with no issues there, try adjusting different network settings and uninstalling any software that might be conflicting with Spotify's connectivity.
Try connecting your desktop to the Internet via a mobile hotspot. If the app works through it, get in touch with your router's manufacturer.
If you're on a non-personal device or network (student laptop, student network, corporate laptop or corporate network), reach out to the administrator for help.
