owa page does not display

Dear all,

I recently installed a new Exchange Server 2013 on ad Windows 2012 R2 and did all the configuration. Mail are going out and in without problems but one strange thing is happening, I cannot open the OWA in a different browser than IE11 and below. 

If I type https://mail.maydomain.com/owa on a firefox, edge, opera it just shows login page and after you type a password it goes blank.

What I'm missing guys, please advise.
