Parent node does not exist issue while starting using server-with-encryption.py
PVenkateshmurthy opened this issue · 1 comments
I am trying to run server-with-encryption.py and start the server via python server-with-encryption.py command from terminal. I got requested parent node does not exist issue.
I tried debugging by keeping a breaking point at
populating our address space
myobj = await server.nodes.objects.add_object(idx, "MyObject"), then I got the below debug report. It says OSError: [Errno 10048] error while attempting to bind on address ('0.0.0.0', 4840): only one usage of each socket address (protocol/network address/port) is normally permitted.
