Dear Mr. Philipp,
You missed one point in scaling property. While one corresponds to length (radius/lattice spacing), the other corresponds to the dielectric contrast. When you changed the dielectric constant from 11.4 to 2.45, obviously, the dielectric contrast got changed and that is the reason why you couldn't observe any band gap (I assumed that you took the dielectric constant of background as 1). You can take the background epsilon in the first case in such a way that the contrast is equal to that in second case and you will get the same result.
regards,
Nagesh.
