When I go to the Notes page on [https://my-nc.example.org/apps/notes/](https://my-nc.example.org/apps/notes/) I get redirected to /apps/notes/note/2452 but I see only an empty page: the background image and menu, but no notes list or notes editor. When I reload the page with ctrl+R, the note is displayed as expected.

When I click the top left arrow pointing to the left, I get my notes list, as expected.

When I click the menu bar notes icon again, I get back to the blank Notes page. The Firefox console shows errors, but I’m not a frontend developer and don’t know if these are important here:

```auto

I am not sure if this started with the last AIO container update to **[Nextcloud Hub 26 Winter](https://nextcloud.com) (33.0.8)** or when updating Firefox (to 155.0.1).

I checked `/var/www/html/data/nextcloud.log` but nothing stands out to me.

I cannot run `occ` as it doesn’t find the php executable; `find / -name php` comes back empty besides `/root: Permission denied` and similar ones for `/proc`. So here is `config.php`:

How can I debug and fix this?

Please confirm in a different browser.

This looks like a CSP problem. Anything in front of your server like a reverse proxy, CloudFlare, etc.?

Thanks, jtr!

I access nextcloud by name, which my local pihole (in its own container, not bundled with nextcloud) resolves to its local IP address (192.168.1.100); no proxy or such.

Firefox 154.0-1 works on Linux, 155.0.1-1 does not work on Linux. Chromium 152.0.7977.64 (Official Build) snap (x86\_64) works as well on Linux. Firefox 1.55.0.1 works on macos. I switched various extensions and settings around, but nothing helped. Weirdly enough I sync browser settings between Linux and macos, so I’d expect to see the same behavior.

Not happy about this, but the workaround of reloading the page will have to do.
