Default dashboard returns blank page upon reload - custom dashboard works

Hi all, recently I started to have this weird behaviour that I can’t really explain. I tried to use the search function but wasn’t able to find anything that helped, maybe wrong search terms… anyway.

I currently have two dashboards:

  • Overview (default, autopopulated)
  • mobile (custom)

  • When I load Overview through its URL (i.e.: http://homeassistant.local:8123/lovelace/0) I get a blank page with nothing showing, also no navigation buttons / menus etc, just a fully blank page. The same happens when I use http://homeassistant.local:8123 without subdirectories in the url and have the Overview dashboard set as default.

  • When I load the custom dashboard through its URL (i.e. http://homeassistant.local:8123/mobile/0) the custom dashboard loads just fine; it also loads fine when I set the custom dashboard as default and use http://homeassistant.local:8123 without subdirectories in the url.

  • When I first load the custom dashboard and then use the sidebar to navigate to the Overview that also works, but when I refresh it again I end up with a blank page.

  • All newly created dashboards show the same behavior as the auto-populated dashboard. I can navigate to them through going to my custom dashboard that still works and then use the sidebar.

Anyone who could give me a advice on what to do to troubleshoot? I was editing my mobile dashboard for a while on my macbook so hadn’t noticed this behavior untill I recently started using my desktop again when working from home, which still had the default auto-populated dashboard set as default dashboard.

I would prefer not to fully start over my HA since id have to redo all my integrations etc also…

Hi Daan, try with another browser to rule out it’s HA or your browser.

In many cases just refreshing the browser is not sufficient and you have to clear the cache or do a hard refresh (CTRL + SHIFT + R on windows, dunno about other platforms)

Unfortunately, I tried and could reproduce this on edge, safari and firefox. Also after hard-refreshing and clearing cache. Thanks for replying though! Hope I can get this sorted.

Edit: this behavior happens on both my macbook and desktop btw so I do think its something in my HA config, just not sure what…

Did you recently add something to that default dashboard or made a change in YAML mode?

I had this happen to me too once and I didn’t bother any further and just created a new one.

What happens if you use http://homeassistant.local:8123/lovelace (without the ‘0’)

No I cant recall that I did. Actually I just noticed my whole frontend bugs out - the only page that I can refresh seems to be my custom dashboard. All other pages result in a blank screen when reloading… (e.g. http://homeassistant.local:8123/config/areas/dashboard, http://homeassistant.local:8123/developer-tools/yaml, and so on). I can navigate to all of them just fine if I first load the custom dashboard, but when I reload whatever page I navigate to, I get a blank screen. This happens in both safari and edge.

Maybe I’m better off starting over with a fresh install and rebuilding my integrations, painful as that is.

Did you restart HA?

Yeah multiple times, as well as the proxmox vm, to no avail.
