Relative residual is greater than the relative error in heat transfer model

I have built a model of heat transfer including conduction, convection and radiation. When the model was computed with coarse mesh, it worked well, but when I refine the mesh, solution returns this error message:

Failed to find solution.
The relative residual is greater than the relative tolerance.

Why did it happen? Any idea?

Thanks in advance.
