Hello everyone!
I just deployed the TAG MANAGEMENT App on a DMA and I'm facing an issue with the displaying of the thumbnails.
On the DMA we created an MCS element and I do see the low-code app retreiving the data properly.
However the thumbnails shown on the Channel Status table are missing:
But actually the thumbnails on the MCS gui itself are properly displayed:
Any suggestions as to why they are not working?
I also add I initially had an issue with the Output video as well: even though on the element creation I flagged the "Skip SSL/TLS certificate verification (insecure)", the video returned a "HTML5 HLS Video Error
The media source failed to load: Network error."
I then had to play the hls URL with VLC and manually accept the certificate.
Once I did that, it started working.
Is this expected behavior?
Thank you for helping!
Hey Riccardo! I recently discovered the MCS Firmware actually impacts how the data of the channel thumbnails is returned. If you have access to the element on cube, can you check two things:
- if Thumbnail in Channel Status Overview is filled in
2. on the Communication > Polling Configuration table (assuming you have the latest TAG MCS driver)
In more recent MCS firmwares, the thumbnail is retrieved separately, and you may need to set the API call of the Thumbnails to 5.13.

Hey Blake!
Thank you, it did the job! I completely missed that part on the driver…I changed to API 5.13 and it works properly.
Thanks again!
