I tried your idea to change the font-files to another. I choose a font where I’m sure that it is working, because this font is actually used at an other website. But unfortunately it doesn’t fix the problem.
I realize that always if I upload my custom font the browser (chrome) use “Open Sans”, Arial, Helvetica, sans-serif even if I delete all settings in Google-fonts and standard-fonts.
