EDAS upload fail: IEEEtran sidemargins_a4 error

When uploading my paper to EDAS I get the following error: The right margin is 1.422 cm on page(s) 4 (widths: 18.1; 18.1; 18.1; 18.1; 18.1; 8.9 cm), which is below the required margin of 1.6 cm for A4-sized paper.

This is my header:

As you can see I added addtolength{rightmargin}{+0.178cm} in my attempt to fix the issue, but the error still occurs. Any ideas?
