grafana.net - site is not usable

[webcompat-bot]

URL: https://grafana.net/

Browser / Version: Firefox 127.0
Operating System: Linux
Tested Another Browser: Yes Chrome

Problem type: Site is not usable
Description: Page not loading correctly
Steps to Reproduce:
Grafana Cloud is broken showing the error:

If you're seeing this Grafana has failed to load its application files

1. This could be caused by your reverse proxy settings.

2. If you host grafana under subpath make sure your grafana.ini root_url setting includes subpath. If not using a reverse proxy make sure to set serve_from_sub_path to true.

3. If you have a local dev build make sure you build frontend using: yarn start, or yarn build

4. Sometimes restarting grafana-server can help

5. Check if you are using a non-supported browser. For more information, refer to the list of supported browsers.

At first I though it was an error with Grafana but I does work in Chrome and Grafana Cloud is not reporting any issues at the moment.

In the console I got the error:
Uncaught TypeError: target argument of Reflect.getPrototypeOf must be an object, got null

We appreciate your report but I was not able to reproduce this issue. I was able to load the page as expected:

Tested on:
• Browser / Version: Firefox Nightly 127.0a1 (2024-04-22)
• Operating System: Linux

Suggestions:
• Clear cache/data/cookies, disable Ad-blocker (if available), or create a new profile (without syncing/importing data) and check again
• If there are any changes made to the default settings of the browser (e.g. in about:config), please revert to the default settings

What made it work for me is disabling the CanvasBlocker extension; uBlock Origin, PrivacyBadger and the default firefox tracking prevention seem to work just fine (Mozilla/5.0 (X11; Linux x86_64; rv:125.0) Gecko/20100101 Firefox/125.0).

For the record, I had the same issue.
It comes from CanvasBlocker extension indeed, but whitelisting the URL is unfortunately not working, because of kkapsner/CanvasBlocker#707
So the only workaround for now is to disable the extension globally (it's possible to install the beta version 1.11 instead, where you can whitelist sites). See also grafana/grafana#65759
