Hi!
Thank you for your reply. Yes, I am sure I properly entered the proxy and pandora password. As I said before I could listen to the music when I checked "Create trial account", so for sure the proxy server password is ok.
If the proxy server supports CONNECT requests - I have no idea... How could I check this? I use this proxy: https://getfoxyproxy.org/proxyservice/index.html - looks quite stable.
I'll check the beta soon and get back.
Michael
