Using “NA” seems to give you a result with a real server. Isn’t that what you want?

Sorry, it is a typo error. Below the corrected changes,
If I use serverCapabilityFilter = new String[]{"DA"};, I am receiving Servers=NULL.

If I use serverCapabilityFilter = new String[]{"NA"};, I am receiving below output.
Servers=[ServerOnNetwork{RecordId=1, ServerName=opc.tcp://localhost:4840-localhost, DiscoveryUrl=opc.tcp://localhost:12686/milo/discovery, ServerCapabilities=[NA]}]
Why is the "LDS" result different than before?
Isn't the result using "NA" showing a Milo server instance registered?
Kevin,
If I use serverCapabilityFilter = new String[]{"LDS"};, I am receiving Servers=NULL.
LastCounterResetTime=DateTime{utcTime=132368633219396840, javaDate=Wed Jun 17 15:58:41 IST 2020}, Servers=null}
If I use serverCapabilityFilter = new String[]{"NA"};, I am receiving below output.
Servers=[ServerOnNetwork{RecordId=1, ServerName=opc.tcp://localhost:4840-localhost, DiscoveryUrl=opc.tcp://localhost:12686/milo/discovery, ServerCapabilities=[NA]}]
It seems only LDS is working properly with FindServerOnNetworks() api service. I do need to do extra coding to retrieve servers on Networks ?.
Thanks, Dhanasekar
Using "DA" seems appropriate.
Ok..If I want to retrieve the OPC UA server running in my networks, I have to mention 'DA' in filters.. Am I correct ??
