@erossignon Thank you very much for looking into the issue.

As mentioned before I cannot run the opcua tests on Windows either since a while. Seems related to some company network settings.

  1) OPCUA Client
       Y1-0 should read a topic with contentType= application/json:
     Error: Cannot connected to endpoint opc.tcp://<HOSTNAME_MY_MACHINE>:7890
msg = The connection may have been rejected by server,

For the record and maybe to help others as well.
By looking at your investigation and fix I did the same on windows updating %WINDIR%\System32\drivers\etc\hosts with the following line

127.0.0.1 <HOSTNAME_MY_MACHINE>

and the opcua tests are working again 👍
@egekorkan you seemed to have the same issue, right?
