F10 map not accessible when hosting

For some reason, since about 2 days ago, clients are unable to access the F10 map on the storm of war server.

 

 

Loading the mission in single player on the server is not a problem.

Loading the mission in single player on another machine is not a problem.

Hosting the mission on another machine is not a problem.

Here are the mission settings:

 

 

And here are the server settings:

 

 

Anyone got any ideas?
