7 months ago I have a similar problem since moving from a raspi to proxmox. Strangely enough it works when I set the global loglevel to DEBUG ?! Switching back to INFO -> blank page
Could you try setting the log level to DEBUG?
But then: Why does it work in DEBUG?
When opening the dashboard in myopenhab.org (https://home.myopenhab.org/) I get only a blank page. This worked before but I have not been using it for some time and now it does not work anymore. I am not 100% sure, but I think I did not try it since upgrading from OH 3.4.2 to OH 4, so it could be that the upgrade broke it.
The issue occurs with Firefox, Chrome and Edge on Windows 11, and also with Safari on an iPad with the latest iOS.
I first experienced it yesterday, since then it has been working sometimes, but mostly I get only the blank page. A refresh (F5) or hard refresh (CTRL+F5 or other, depending on browser) does not help, the page remains blank. I also tried clearing out the cache and all site data, but it did not help.
The source code of the blank page looks like this:
<!doctype html><html><head><meta charset="utf-8"><meta http-equiv="Content-Security-Policy" content="default-src * 'self' 'unsafe-inline' 'unsafe-eval' data: gap: content: blob:; style-src 'self' 'unsafe-inline';"><meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,minimum-scale=1,user-scalable=no,minimal-ui,viewport-fit=cover"><meta name="theme-color" content="#e64a19"><meta name="format-detection" content="telephone=no"><meta name="msapplication-tap-highlight" content="no"><title>openHAB</title><meta name="apple-mobile-web-app-capable" content="yes"><meta name="apple-mobile-web-app-status-bar-style" content="black-translucent"><link rel="apple-touch-icon" href="[/res/icons/apple-touch-icon.png](view-source:https://home.myopenhab.org/res/icons/apple-touch-icon.png)" type="image/png" sizes="180x180" crossorigin="use-credentials"><link rel="icon" href="[/res/icons/favicon.svg](view-source:https://home.myopenhab.org/res/icons/favicon.svg)" type="image/svg+xml" sizes="any" crossorigin="use-credentials"><link rel="icon" href="[/res/icons/128x128.png](view-source:https://home.myopenhab.org/res/icons/128x128.png)" type="image/png" sizes="128x128" crossorigin="use-credentials"><link rel="manifest" href="[/manifest.json](view-source:https://home.myopenhab.org/manifest.json)" crossorigin="use-credentials"><link href="[/css/app.e4469a9e02bf8bc86419.css](view-source:https://home.myopenhab.org/css/app.e4469a9e02bf8bc86419.css)" rel="stylesheet"></head><body><div id="app"></div><script src="[/js/app.e4469a9e02bf8bc86419.js](view-source:https://home.myopenhab.org/js/app.e4469a9e02bf8bc86419.js)"></script></body></html>Please let me know if there is any further information that I can post.
