Macbook not able to find any cast device

My Macbook pro is not finding any casting device like Chromecast and Mediabox. I tried using Google Chrome from macbook and VLC player. No cast device detected.

The same cast device can be detected and worked perfectly using Iphone, Andriod Phone, Windows laptop.

Tried everything available in the open internet but nothing thing works.

Ran hardware diagnostics in mac. Everything is Ok.

Note: The same macbook was able to cast to chrome-cast 14 days back. After that I installed cisco vpn client and checked recently to cast and its not working. Removed vpn software but still no casting device. Not sure if the vpn software had any impact or changed any settings which I am not aware of.

Please find attached the screenshot to know more on the current state of the macbook in terms of firewall.

Hello sagarnil,

Thank you for using Apple Support Communities! I understand that your MacBook Pro no longer detects casting devices after installing and uninstalling a VPN. I would be happy to help point you towards a resolution.

Using the same Wi-Fi network your other devices are connected to and working with your casting devices over, let's create a new network service on your Mac. Connect the Mac to Wi-Fi using this newly created network after:

Manage the Wi-Fi connection on your Mac

If the Chromecast device or MediaBox still isn't detected when using the new network, I suggest running through the following troubleshooter form, then suggested steps next:

Device discovery troubleshooter

No Cast Destination Found? - Chromecast Help

You may also want to further test if the issue occurs in another user account on your Mac. If you don't have another user account, here's how to create one for testing:

Cheers!

Hi ,

I have doubt in this step:

Using the same Wi-Fi network your other devices are connected to and working with your casting devices over-- This is correct my windows machine, iphone is working and also andriod.

let's create a new network service on your Mac. -- done

Connect the Mac to Wi-Fi using this newly created network after: -- how is this possible?. If I am creating a new network like "sagarnil’s MacBook Pro" using channel 11 and getting connected to it will have no internet, no casting device found.

I have go though all the steps in the below links but it did not help. I have already tried this earlier.

Device discovery troubleshooter

No Cast Destination Found? - Chromecast Help

My andriod phone, Windows machine, iphone can find the chromecast but not my macbook.

I have already tested with a different macbook account. No casting device found. Its not an account specific issue.

Do you have any other steps I can follow?
