@alexiskhoury I made an attempt to run 0.12 and 0.13-SNAPSHOT (current
develop) wit prosys simulation server, both looks fine. For me root cause of
troubles (why it didn't work in first run) was extra trailing slash after
`OPCUA/SimulationServer`. The endpoint matcher is strict, so it looks for exact
match.
Can you share log or strack trace you get?
Example program for 0.12+ releases:
```
String keystoreParams = "discovery=true"
+ "&application-uri=urn:apache:plc4x:client"
+ "&negotiation-timeout=60000"
+ "&security-policy=NONE"
+ "&message-security=NONE";
try (PlcConnection connection = new
DefaultPlcDriverManager().getConnection("opcua:tcp://arch:4840/OPCUA/SimulationServer?"
+ keystoreParams)) {
CompletableFuture<? extends PlcSubscriptionResponse> future =
connection.subscriptionRequestBuilder()
.addChangeOfStateTagAddress("c", "ns=0;i=2258")
.build().execute();
future.whenComplete((r, e) -> {
if (e != null) {
e.printStackTrace();
return;
}
r.getSubscriptionHandle("c").register(event -> {
for (String field : event.getTagNames()) {
System.out.println(field + " " +
event.getObject(field) + " " + event.getResponseCode(field));
}
});
}).get();
Thread.sleep(60_000);
} catch (PlcConnectionException e) {
throw new PlcRuntimeException(e);
} catch (Exception e) {
e.printStackTrace();
}
```
