title: Shiny app does not work on Microsoft edge browser
body: <p>we have developed a shiny dashboard. It is a combination of flexdasboard and shiny app. The dashboard was implemented on shiny server (free version, see below for more details).</p>
  
  <p>The dashboard works fine on chrome, firefox, edge and internet explorer when accessing it through 'servername:3838/dashboard'. </p>
  
  <p>However, when we try to access the dashboard through '<a href="https://dashboard.company.com:3838/dashboard" rel="nofollow noreferrer">https://dashboard.company.com:3838/dashboard</a>' it works on chrome, firefox and internet explorer but not on edge.</p>
  
  <p>Any ideas where the problem could be?</p>
  
  <p>Below are some details on the system we use.</p>
  
  <p>Thanks</p>
