YouTube blocked when logged out

harms32

Hi I have a strange problem. If I try to watch a video on YouTube it loads the side normally, but the video shows only 0-1:33 min, doesn’t start and after a while it shows an error message.

If I log into an YouTube / google account and watch the same video it works perfectly.

I already disabled and also removed pfblocker. And there are only firewall rules to prevent connections between vlans in place.
I also disabled blocking bogon networks at wan settings, but no luck.

Do you have any idea what I am doing wrong?

I’m running pfsense 23.09.1-Release on an dell r210.

Something is missing : your Google Youtube account is the premium one ?
If not, I suspect that Yutube tried to insert a publicity, and loading of the publicity failed.
or : not playing the publicity, or not getting the publicity, and you won't get the 'can continue' cookie.

I'll say upfront : I'm making this one up. But if I was working for Youtube, that's how I would do it (so they continue to pay me (well)).

Maybe nothing.
Maybe you have another admin above your connection that want you to do a favor by blocking some 'publicity' source IPs .....
Or, the video you're watching contains ... I don't know, something else, as I don't know how video playing actually works in general, or specially with youtube ready readers : is their meta code in the video stream ? Is the browser using java or something like that ? Maybe it('s the device /software that you are using has a bug ? Does it happen on all your devices ? Your network ?

What was the error shown ? Errors are very important, why not showing it ?
Example : if the error was "Your device just ran out of memory" we might be able to explain you what happens and you had a solution right away.

@NightlyShark : your proposal rings a distant bell.
Can you develop ?
Your solution, if it is one, is very deeply buried in the system. Drivers don't know what Youtube is ...

Yes.

Maybe nothing.

I think this was kind of the case. I did not change anything and the problem disappeared.
But thank you all for your suggestions. @Gertjan @NightlyShark

@Gertjan It could actually boil down to the DNS server used... If it's PfBlockerNG, PiHole, AdGuard or a customized OpenDNS profile... Certain CDNs that interplay with usage trackers and adverts might fail...

@NightlyShark
Pfblockerng was used. But I removed it temporarily for testing. It did not help.

NightlyShark

@harms32 I don't suppose you also run Snort/Suricata in block mode?

NightlyShark

@harms32 Also, after removing it temporarily, did you perform an

ipconfig /flushdns

and

netsh winsock reset

and reboot?

NightlyShark

@harms32 Re-read your opening post... Also try performing a deep cleanup of your browser cache.

@NightlyShark

No Suricata/ Snort

No I did not. But I will keep it in mind if the problem comes back.

As of right now, everything works.

Thanks again @NightlyShark
