Leaking coolant from this drain plug any suggestions on how to fix it ?

Recent got a new turbo 16g leaking coolant from below the banjo bolt.

Any help on how to prevent it from leaking ?

Will have to pull the turbo, not only to verify that it's actually leaking from there and not weeping from the banjo bolt itself, bit to repair if needed.

I believe that's a freeze/expansion/core plug.

Looks like it may be an optional lower coolant port to me. I think they use an allen key, try to tighten it up.
