My control point can't see MinimServer - after a while

[simoncn]

MinimServer uses ports 9790 and 1900, together with other ports that are dynamically allocated at runtime. It doesn't use ports 80 and 5000.

As the control point is discovering MinimServer initially, it seems that UPnP "alive" messages and/or subscription renewals are not being passed correctly between MinimServer and the control point. Which control point are you using and what device are you using to run it?
