Why can I only access 2 specific pages via a VPN, but the pages work on other devices in the same network?

I have 2 Fritz at home! Boxes (7590 and 7362SL as mesh repeaters).

On this network, A. 2 notebooks, 3 cell phones and a desktop computer connected to the mesh via WLAN.

On the desktop computer, the mobile phones and a notebook, I can access and use Facebook and YouTube via the browser without any problems.

On a notebook, however, I have the following problem:
- With Firefox, I only see a white page on Facebook
- I can call YouTube, I also see the preview gifs for the videos, but when I click on a video, only the loading bar rotates and nothing happens.

Before, everything on the notebook worked normally. I undid all Windows updates and nothing else was changed on the device. No new programs have been installed.

No tools such as a firewall or virus protection are installed on the notebook. Only the standard tools that are included with Windows 10 anyway (Windows Defender).

Tests with multiple virus / malware tools have not found any suspicious software.

I have already reset the Wi-Fi network in the settings. All data such as cache etc. Deleted in the browser, new profile created and even the entire browser uninstalled and reinstalled.

Facebook and Youtube also do not work on the notebook with the Edge Browser, Opera, Chrome.

The Fritz! Box is also set to perform a forced separation every 24 hours (at 5 a.m.). This gives me a new IP address. Which is why I can exclude any blacklists from Facebook and YouTube.

If I were on any blacklists, they would also block my account.

The strange thing: When I work from home and I'm connected to the VPN via OpenVPN, the two sides work without problems.

Does anyone have any idea why this might be?

Sensational! Thank you very much… Deleting the WLAN profiles helped…
