My Proxmox node has suddenly stopped showing the web GUI. I'd like to figure out how to fix it. When navigating to the IP, I'm met with this blank page:

Code:
<!DOCTYPE html>

  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <link rel="stylesheet" type="text/css" href="/pve2/css/ext6-pve.css?ver=5.4-13" />
   
    <script type='text/javascript'>function gettext(buf) { return buf; }</script>

    <script type="text/javascript">
    Proxmox = {
    Setup: { auth_cookie_name: 'PVEAuthCookie' },
    defaultLang: 'en',
    UserName: '',
    CSRFPreventionToken: 'null'
    };
    </script>
    <script type="text/javascript" src="/proxmoxlib.js?ver=1.0-28"></script>

    <script type="text/javascript">
    if (typeof(PVE) === 'undefined') PVE = {};
    Ext.History.fieldid = 'x-history-field';
    Ext.onReady(function() { Ext.create('PVE.StdWorkspace');});
    </script>

  </head>
  <body>
    <!-- Fields required for history management -->
    <form id="history-form" class="x-hidden">
    <input type="hidden" id="x-history-field"/>
    </form>
  </body>
</html>

The HTML you get looks okay.

Do you have Javascript enabled?
Which browser are you using?

Try to empty your Browsers caches and/or try a different browser to see if it works there.
 
I've confirmed on some other sites that use Javascript (eg. whatismybrowser.com/detect/is-javascript-enabled or enable-javascript.com) that it isn't disabled in the 3+1 browsers I've tested:
  1. Windows Desktop Computer
    • Chrome - Version 77.0.3865.90 (Official Build) (64-bit)
    • Internet Explorer - Version 11.737.17763.0
    • Firefox - Version 69.0.2 (64-bit)
  2. Windows VM from within Proxmox node in question
    • Chrome - Version 77.0.3865.90 (Official Build) (64-bit)


I've also tried emptying cache, DNS, and incognito/inprivate modes which leads me to believe there's something wrong with pveproxy or related.

If it helps, this is what Chrome's console is outputting when it loads the page:
Code:
(index):17 GET https://node:8006/pve2/ext6/ext-all.js net::ERR_ABORTED 501 (got short file)
