I use UpnpIgdPortMapper,but throw a java.lang.IllegalStateException when call a mapPort,this is my log java.lang.IllegalStateException: null at com.offbynull.portmapper.mappers.upnpigd.PortMapperUpnpIgdPortMapper.oldMapPort(PortMapperUpnpIgdPortMapper.java:276) at com.offbynull.portmapper.mappers.upnpigd.PortMapperUpnpIgdPortMapper.mapPort(PortMapperUpnpIgdPortMapper.java:134) at leason.core.nat.NatClient.$anonfun$addMapping$1(NatClient.scala:23) at cats.effect.internals.IORunLoop$.step(IORunLoop.scala:176) at cats.effect.IO.unsafeRunTimed(IO.scala:321) at cats.effect.IO.unsafeRunSync(IO.scala:240)

btw,I test mapPort using NatPmpPortMapper,the log shows success,but I can't telnet the port,I'm a little confused...
