I developed one application in windows phone 8.1 using VS 2013. After creating "appx" i am not able to install on my windows phone tablet.This tablet does not have facility to connect through USB. So i used wifi to connect. I want to install this application on my tablet  so i am trying to open store to install application using locally option but store is not opened it gives me error 

We were unable to connect to the store. This might have happened because of a server problem
