Not able to connect services running inside docker container from remote host

i deployed the app container in docker-ce. i am able to access the services from localhost but when i am trying to access the port from remote host. its not able to connect.
in earlier versions of docker it was not the case. i was able to connect .
since both versions of docker are mapping on tcp6 host port. it should not be the case.
not sure if i am missing something

can u add more details on how you are starting the service and network details.
