http://man7.org/linux/man-pages/man7/socket.7.html Assuming you are using AF_INET addresses, SO_REUSEADDR will not let you bind() to an address if the same is already bound to an _active listening socket_. Also, SO_REUSEPORT option is required for all the socket that are bound to the same address, maybe the address you are trying to bind() to was already used by a socket that has no SO_REUSEPORT option set.
