OPC server on windows embedded

Hi!
I've got a proface's HMI on windows embedded, i've install ABB OPC server on this HMI.
When I scan the network, i can find the robot but when i try to connect the OPC client to the OPC server I've got an error (80040153).
I try with IWS HMI software and with an OPC client explorer, ans this two software can't find the OPC server.
Everything works fine with my laptop (windows 10). Do you know if there are some limit with Windows embedded and the ABB OPC server?

best regards
