[solved]Cannot connect to daemon after disable adapter and reenable

after disable my Ethernet adapter because the IPv6 issue, after I enable it but remove IPv6 support , the docker daemon seems unreachable

Error response from daemon: dial tcp 10.0.75.2:2375: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

resolved after exit docker and reopen it.
