If after executable name you have UNK, then you have wrong game data files. You have downloaded BF4 from site, which does not support ZLO multiplayer. Repair files on ZLOrigin, if that does not help then reinstall BF4 completely.

If after executable name you have OK, then try to join other servers and see if you still have black loading screen.
If you don't have black loading screen on other servers, then it's the server issue. There is nothing you can do about it, except notifying the server admin. He may have closed ports or some other issue.

If you still have black loading screen on all servers, then
