connection problem - by: sarg314

Last Saturday I was able to use the Android app to initialize my stellarmate. I was able to connect to 10.250.250.1 with my ubuntu laptop and access the vnc.html page, star k-stars, etc. Today I cannot connect from the laptop. The android app still works and I can connect to the vnc.html page through that - everything works on the android device. My steps are:

1- Connect to stellarmate via android app and use it to start the server. (is this necessary?)
2- disconnect android app
3- Connect laptop to 10.250.250.1 hotspot
4- send chrome browser to 10.250.250.1:6080/vnc.html
It goes busy for a while and then says "site cannot be reached. 10.250.250.1 refused connection"
I can ping the 10.250.250.1 network from ubuntu, so the basic connection seems to be there.

Any suggestions on what to check next?
Thanks,
