App on android 5.1 - external login repair

I have radio streaming app (icecast) with a few stations. Access to stations is login protected. There is .htpasswd authorisation on Icecast server. All stations have this same common credentials. You are logged to all stations if you was logged to one. There is a popup with login implemented to this app. User logs to one of the streams directly before use players. He can use any station's player next. Its work propertly on Android 4.1 to 5.0. There is problem on Android 5.1. I can open url and login in Firefox but no in my app. Login is incorrect. You can see error :"Username and password doesn't matched", but its really matched. As I see in debbuger there is error: "[login to view URL]: android_getaddrinfo failed: EAI_NONAME (hostname nor servname provided, or not ". Its possible that it should use AsyncTask or similar to perform the network request. I'm sending in attachment [login to view URL] include login activity. Additionaly there is link to the full app source: [login to view URL] Test login:ziutek password: fiutek I need fix is ASAP.
