Yes, that's precisely why I have asked these questions and what I expected.

What happens there is that the endpoint URL returned by the server is not usable outside its local network. Version 5.32 has a different default behavior and replaces the host part in the endpoint URLs returned by the server by the host part provided by you originally. It is possible to achieve the same in 5.30, but the default behavior in 5.30 is to use the endpoint URL as it is returned by the server, without change.

Best regards

1) Is opc.tcp://14.1.2.164:49323 also accessible from the outside network ?

2) Is there any reason why you don't upgrade to version 5.32? (it's free of charge if you are licensed to 5.30, 5.31).

Best regards
