Nextcloud official web page is blank when ad-blocker enabled

If I open this page with uBlock Origin enabled:

I’m getting a blank page, and this error message in the console:

I’m sure it’s an overlook but for an organisation that champions user privacy, it doesn’t look good to serve blank pages just because the user has an ad-blocker.

@laurent Just to be sure, did you check the same page again later? I’ve noticed the site going down for brief periods several times this year, so you may have been unlucky in timing.

Otherwise: I currently have no trouble accessing or displaying the page you linked.

I’d love to fix it, but I’m simply clueless on how, sorry :cry: suggestions/pull requests welcome!

@laurent I cannot consent to your claim and would like to ask for more details.

As of today my browser has access and the full page is visible.

  • Firefox 68.2.0esr with add-on uBlock Origin v1.22.4
  • Annoyance filter is activated.
  • No whitelisting of in my setup.

May I suggest the option you could check your setup and could seek to optimise your local filtering?

IMHO it could be sufficient to just whitelist the website (see below).

Local workaround as a user:

  2. Plain hostname
  • whitelist all pages from or above (i.e.,,
