Windows 10.
Calibre 6.9.0
ERROR: Failed to start content server: The content server could not be started. Mistake:
No socket could be created -- (('192.168.1.44', 8080): [WinError 10013] Attempt to access a socket not allowed by its access permissions)
I close the prompt and everything seems to work fine.
I rectify.
Naturally, I can't start the server.
Fixed: I have changed port 8080 to 8081.
