RSS Ticker's stop working

We use Xibo 4.1 (self hosted in Linux Ubuntu Docker) and the latest Windows player.

Suddenly the RSS stopped working. We had this before; then it was an error in the player.
Now in de layout we made the RSS Ticker just says; unexpected error.

RSS keeps returning this.
In the Log’s we see this messag:
98703 bfea1e9 2024-09-28 23:58 XMDS POST ERROR XIBO-SRV GetData getData: Failed to get data cache for widgetId 1482, e = Cache not ready

98733 f9243a6 2024-09-28 23:59 PLAYER POST ERROR XIBO-SRV [DataAgent] DataAgent Run: Exception: Cach

It started the 29th of september. How to resolve this isseu? Better said, how can we stop this comming again?

If we edit the feed, it looks like it is working fine; when we use an other feed.
