PENDING Failed to get MCS key (Code 0x80004005)

[juannabis]

Hello, I try to use multicast, but I have problems.

"Failed to get MCS key (Code 0x80004005) ApplyOperatingSystem 13/06/2020 9:28:25 1188 (0x04A4)"
"ClientRequestToMCS:oRequest failed. error = (0x80004005). ApplyOperatingSystem 13/06/2020 9:28:25 1188 (0x04A4)"

What is my problem?

Thank you.

Do I have open the ports for multicast?

SMB - TCP 445
Multicast Protocol - UDP 63000/64000

The log says multicast open session request failed. This means the multicast is not working. This could be either due to the firewall, security software preventing it or something else. If you have a network team in your organization, contact them and report this issue.
