Problem
When trying to bind the socket on a port that is not being occupied, the following permission error occurs:
ERROR: [Errno 13] error while attempting to bind on address ('127.0.0.1', 80): アクセス許可で禁じられた方法でソケットにアクセスしようとしました。
ERROR: [Errno 13] error while attempting to bind on address ('127.0.0.1', 80): attempt to access a socket not permitted by its access permissions
Solution
Method
- Seems like it is because Hyper-V reserves some random port ranges, need to restart WinNAT service to make Hyper-V re-select the ports randomly.
Code
net stop winnat
net start winnat
