Answer 1

Yeah, this happens when your hostname settings are detected incorrectly. Log in to the server where the database runs, and run:
lsnrctl status
You will most likely see that the listener listens on localhost/127.0.0.1, and not on the address which is reachable from the network.
Locate the listener.ora file (the lsnrctl status command displays the full path to it), edit it, e.g:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.0.2)(PORT = 1521))
)
)
Then restart the listener.
lsnrctl stop
lsnrctl start
Or use the "Services" management console in Windows to restart the listener service.

Context:
LSNRCTL for 64-bit Windows: Version 12.1.0.2.0
Steps:
lsnrctl stop
Change listener host from localhost to specific server IP
Sample path: C:\app\root\product\12.1.0\dbhome_1\NETWORK\ADMIN\listener.ora
lsnrctl start
for check: lsnrctl status

Check that the IP address and port of the server machine is correct and that you can ping it from the other machine. If it is correct and you can ping it, you need to reconfigure the firewall that is preventing you connecting on that port. It could be a firewall on the server itself, or somewhere else on your network.
