UaExpert (1.5.0) doesnt find server registered in LDS

Post by k47s »

Hello,

I have a problem with UAExpert:
In version v1.5.0-319 the UAExpert doesn't display any OPC UA server that are registered in the Local Discovery Server.
On version v1.4.4-275 it works perfectly.

The log doesn't show any entries when rebrowsing the "Local" node in "Add Server"
Is this a known problem?

Thank you very much

Hello k47s,

with version 1.5.0, we added support for FindServersOnNetwork to the 'Add Server' dialog. It first tries FindServersOnNetwork, if this returns an error, FindServers is called, if this also doesn't work, GetEndpoints is called.

It is possible that your LDS supports FindServersOnNetwork but doesn't return any servers, this would lead to no servers being shown.

We are using the default LDS of the OPC Foundation (latest version).
Which LDS are you using?

Hello k47s,

the latest LDS of the OPC Foundation returns the registered servers as expected. You might want to create a Wireshark trace of the communication between UaExpert and LDS to see what is being returned by the LDS.
