My Question or Issue

Hi All,

I have been trying to troubleshoot why I can't cast Spotify from my mobile or Windows 10 laptop to my Chromecast Ultra (hangs on connecting, I see the Spotify splash screen on Chromecast for 10 seconds and that is it), although I can cast everything else successfully.

I am very technical user and I have went through the usual reset/restart every device on my network without success.

The only strange thing I noticed is that I can't connect to https://apresolve.spotify.com/, it just times out. I have tried everything I can to get that working without success. I can connect to http://apresolve.spotify.com/ (non-secure) though.

This is also preventing the Web Player from working as well.

I have noticed that it works fine if I connect to a VPN in France.

I have even asked my ISP to change my public IP address, without success.

apresolve.spotify.com resolves to 185.37.36.61 on my network.

when I connect to the VPN, it resolves to 104.199.64.136.

So I added an entry in my hosts file to point apresolve.spotify.com to 104.199.64.136, and the Spotify web player works absolutely fine, without the VPN.

I believe whatever is running on 185.37.36.61  is not working and is causing trouble.

This could be the reason why I can't cast to Chromecast.

Any help from the Spotify team is much appreciated.

I think this issue is related to my DNS service, it is resolving the wrong IP address for some reason.
