Disconnected every match (World Tour Silver Superstars League 4)

In FC 26, every match in World Tour Silver Superstars League 4 disconnects after a few minutes. I am not fully disconnected from EA servers. The game sends me back to the event menu, not the main menu. The match attempt does not count.
This happens every game, no matter if I am winning or losing. My internet connection is stable and other online games work fine.

This makes the event unplayable. Please confirm if this is a known issue and if a fix is planned
