Problem with player.vimeo.com

It looks like you are using an ad blocker. Try disabling it for kodekloud.com and vimeo.com

hi all video on CKS cannot be played

I have disabled Ublock and Adguard but it didn’t fix the problem. As it is shown in the image, if the internet is not secure player.vimeo.com can’t be used.

It is working for me. Try private/incognito mode.
Also work through Vimeo troubleshooting pages Desktop browser – Vimeo Help Center

I have also heard of Vimeo being blocked by some service providers in some countries. I am guessing you are from Vietnam by your name. Perhaps @trung-kodekloud can shed additional light.
