Lumped port help

Hello,
I am trying to simulate a simple model of a co-planar waveguide on top of a substrate, as seen in the attached file. Whenever I try to compute my result I get the error:
Uniform lumped port should be placed between two conductive boundaries. - Feature: Uniform Element 2 (ue2) - Feature: Uniform Element 1 (ue1)
I do not understand why that happens. I made sure to select the neighbouring boundaries as PEC and set up my Lumped ports based on option two from here: https://www.comsol.com/blogs/modeling-coplanar-waveguides
Could you kindly explain to me what I am doing wrong?
Best Georgios

- Your PEC (set by default) zy planes at x = -2250 µm and x = +2250 µm are shorting out your lumped ports. So those planes should probably not be specified as PEC.
- There may still be other important issues in your model that need to be addressed, but fixing the above will eliminate the error message you reported.
