Problem with conntent after updating server. Red displays, no uplouds

Hello.
We have been using Xibo for almost two years. There were no problems at that time.
But with the server R4 ~4.2.2 update and I think one earlier one, we have some problems.
All displays, even those that are turned on, are on a red background. No one is green like in previous versions.

I found a topic with a similar problem, but I think the solution doesn’t work for us. Display Windows in Red Status - #5 by davide.siciliano

I am attaching an information page from our Windows player.

Thanks for helping solve our problem.

The interesting thing is that when I want to use an old layout, the Xibo player will display it, more or less in a good way. But when we create a new layout. Xibo only displays a screen with the Xibo logo.


I think thats from R402.
