LDS returns wrong discovery url of registered opcua-asyncio server

[JaFeKl]

Hello,

I'm currently having the following issue:
I am using server.register_to_discovery(discovery_url) successfully to register to an open62541 LDS.
The LDS runs on port 4840.
The registered server runs on port 4844: INFO:asyncua.server.binary_server_asyncio:Listening on localhost:4844

When I create a client and use client.connect_and_find_servers() the following information is returned from the LDS:

INFO:adapter_opc_ua: ApplicationUri: https://test/my_application_uri
INFO:adapter_opc_ua: ApplicationName: FreeOpcUa Python Server
INFO:adapter_opc_ua: ApplicationType: ClientAndServer
INFO:adapter_opc_ua: DiscoveryProfileUri: None
INFO:adapter_opc_ua: DiscoveryUrls: ['opc.tcp://localhost:4840']

However I would expect to return the discovery url opc.tcp://localhost:4844 such that I can in the next step fetch the endpoints to connect.

If I do the same client approach with open62541, the LDS returns the correct informations:
Server[1]:
Name: FreeOpcUa Python Server
Application URI: https://test/my_application_uri
Product URI: urn:freeopcua.github.io:python:server
Type: Client and Server
Discovery URLs:
[0]: opc.tcp://localhost:4844

What could be the reason for this? What could be the reason for this mismatch?
