Fonts not available

In TC CK I installed the Raleway font (FontSquirrel) and the family is available.
I assigned ralewayregular to the body text: see Image 01.

The previews shows the body text correctly, formatted with ralewayregular.
Nevertheless, the ralewayregular font seems not to be available when I see the website. See Image 02.

It acts as if fonts have not been loaded.
You can see it on my test site .
This happens even if I use another font and also if I assign the font to titles.
How can I fix it?

Hi
do you have this problem only with this font, or with all addtional fonts ?

I tried both Raleway and Poppins.
Note that in the past I used Raleway in another site ( www.sitiwebgorgonzola.it ) and it is still working.
But in www.sitiwebgorgonzola.it the rule made by Template Creator CK was and not (without the ' both at the beginning and at the end), as Template Creator does in fima.testsrp.it .
Can this make the difference? It should not, IMHO, since there are neither blank spaces nor other strange characters.

the ' shall be ok. The fact is that the font files seem to be not loaded
on the other website, did you use the same font KIT ?

No, I didn't: I used a newly generated webfontkit from Font Squirrel.
So, in Template Creator I deleted the Raleway font and installed the same webfontkit from sitiwebgorgonzola.it.
But the problem is still here.

give me your font kit please so that I can test it
