This tells me you likely have imported this model.

Look closely at the red point highlighted and you will see a geometry problem.

To fix imported geometry for meshing some time needs to be spent in import data doctor.

The dialog you are seeing will highlight the problem areas, so you know where to fix the model.

Then use data doctor.
