OWA is not working in any browser after login page

I'm using exchange server 2013 on windows server 2012..

From last 2-3 days Google chrome got a new update and due to that update while opening owa on Google chrome it shows blank page after login..but working fine in Mozilla and safari

But while I'm trying to fix this issue ...according to one forum I have updated owa & ecp via a command in power shell..

But after that update a new problem arised now after login page is still blank but showing loading on tab status.  .now not working in both chrome as well as Mozilla..

Below is the command after which this problem starts.
