Port in use

After installation via docker on qnap and start I periodically get

OSError: [Errno 98] Address in use

Same what I found here and should be corrected there.

https://github.com/home-assistant/netdisco/issues/216

Any hints, why this occurs compared to the link?

O.k. saw, that the correction was for netdisco/daikin.py and here the same occurs for pydaikin/discovery.py.

But the errors sound similar.
