For the last weeks, I can't log in into my desktop version of Spotify. It says that there is a Firewall blocking Spotify, and to change the proxy settings, and there's nothing I can do to log in. See attached screenshot. I usually use a Macbook, but I have also tried a PC unssucessfully. It's happening in different computers. I can't access it. I am able to log in to the Web Player but there is a lot of functions (like starting a collaborative playlist) that I can-t do on the Web Player.
I have also tried restarting the system, uninstalling and installing back Spotify and different computers. No way to log in to the desktop version.
Any help, please? I am really frustrated.
