I see your broker log into current game 569 But after logging in, the server doesn't receive any messages anymore.
After a while, the server disables the broker: "Disabling unresponsive broker Mertacor2019".
It doesn't seem a problem on the server side.
I would look into the fact that your broker doesn't offer tariffs.
I'll hold the games scheduled for your broker.
Let me know if you need anything else.
