I have this problem with Spotify, yesterday in the application a pop-up message appeared, when I closed it it opened a Web page and I suddenly understood that there was something wrong. Today the application started to work bad and at some point I couldn't play any song. So I uninstalled the application.
When I tried to go on the Web page ( https://www.spotify.com) it says that the website can't be reach, but if I type it without https:// another page opens (see the picture)
This thing happen with any browser and only with Spotify.
Do you have any idea what is going on? Avast doesn't say anything about viruses or else.
