You might want to bump up the timeout to a higher value and see what happens.
In the Kodi folder in Appdata, go to userdata/addon_data/pvr.stalker/ and modifiy the settings.xml file
Find the connection_timeout, and change the 60 to something higher. One member that lives in Thailand had reported using a number as high as 300 as necessary for him to connect. Don't verify the timeout settings on the actual settings page, because it will reset that value to 0.
If it doesn't work at that point, send me the text of the settings.xml to me via pm, and I'll see if there something wrong with that configuration.
