same time...... same date...... command..

machine A , machine B :  url  is available..
machine C : url is not available

What should I check?.......

[dstftw]

Do you check it from the same machine?

[kidol]

You can solve it by replacing

https://r7---sn-n02xgoxufvg3-2gbl.googlevideo.com

with

https://redirector.googlevideo.com

in link 3.

The redirector subdomain will always redirect to a working url (no more white page).

As for the reason for white page: One cause is that a video might be blocked in the country related to the requesting IP.
