Any help would be highly appreciated

Answer 1

Make sure:
1- the listener is started
2- provide correct SID or Service Name: meaning, if these 2 are different dont use the name of the SID while checking the Service Name checkbox.
3-make sure you have the ping of the server you are reaching (direct access, if not do the tunneling)
4- make sure you are using the correct port
5- make sure you are not using PDB and you have created your own database! (PDBs always go south)
These are the reasons you see that error
