How can i make more than one OPC UA server on my windows 10 machine

[HaythemLtifi]

Hello , i am using this URL opc.tcp://localhost:4840/freeopcua/server2/
it works fine , to test my monitoring app i need another OPC UA server but i get an error saying port 4840 can only handle one connection.
thankkkkks

typically 4840 is the iana port which should be the port of the local discovery server if there are more opcua servers on one device. simply choose a different port for the second server!

Thanks a lot as always it was as simple just changed port 4840 to 4841 .
