Possibly due to a recent change on the server, (bigger EPG?) PVR Stalker is having problems connecting, so you need to extend the timeout. Look for the settings.xml for the PVR.Stalker addon_data and change it manually to a number greater than 60.
Visiting the server via a browser will get that message. It's normal.

You ask the right people and community, and you get the right answer.
Thank you Dara! Indeed, timeout was the issue. Per your prescription, I changed it so something greater than '60',
(I selected 120), and it eventually connected (... I would say around 35 seconds, or so).
Glad to also know that the "STB Blocked" message in a browser is something that I can ignore.
I was tearing my hair out for the past week. LOL
A patch to the client seems necessary (to extend the enumeration to larger timeout values), but it was not a big deal to vim(1) the user settings.xml file manually.
Thank you so much again!
