I’m having this problem when i try to connect to the CMS in an Android box.
“Client Register Error in Register: null”
It seems that only happens with a type of WiFi, in the device I have network and I can navigate, but it doesn’t connect to the CMS. When I turn on my mobile internet data on, it connects perfectly. This happened to me twice in different locations, and both of them under the same Internet services company. I don’t know if it’s an open/close ports problem.
