UDP Cannot Assign Requested Address

UDP Cannot Assign Requested Address

I want to open a Datagramsocket and send some packets to my network
device. However when i use the following cood an exception is thrown
saying: Cannot Assign Requested Address: 192.168.1.114:1900
Poco::Net::SocketAddress sa("192.168.1.114",1900);
Poco::Net::DatagramSocket dgs(sa);
std::string text = "hello";
dgs.sendBytes(text.data(),text.size());
What's the problem here. I also use a udp testing software to test the
receiving end if it's capable to receive udp packets on this port and it
works, however with the poco code from above it does not work.
kind regards
