Custom Fonts // CORS works

Hi there,

I’ve seen there are a ton of “can’t add my custom font” posts. Sorry to post another one.

It looks like the solution for pretty much all of them was related to CORS and setting an access control policy.

So I have set that up and verified it works.

When I curl my font with Klaviyo as Origin I get a success response and can download the font-file.

curl -v --request GET 'https://mydomain.com/path/to/my/font.woff2' --header 'ORIGIN: https://klaviyo.com'



> Host: mydomain.com
> User-Agent: curl/8.6.0
> Accept: */*
> ORIGIN: https://klaviyo.com

On Klaviyo I still get the error “One or more font files could not be accessed.”

Running Shopware 6 on an Apache2 webserver. This is my access control policy in my .htaccess in public root directory:

<FilesMatch "\.(ttf|otf|eot|woff|woff2)$">
  <IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
  </IfModule>
</FilesMatch>

Any suggestions?
More insight on the error would also be helpful if anyone from Kalviyo Staff is able to provide it.

Thanks!

Nico

Hey @CP-Nico, I believe your CORS headers setup is incorrect. You get a 200 in CURL but this is not indicative of how a browser would behave.

The easiest way to verify that you have a CORS issue is to call “fetch(URL)” in the browser dev tools. I've posted a screenshot to demonstrate that I am seeing a CORS error in trying to load this font URL from a browser.

It appears your server is not setting the Access-Control-Allow-Origin response header properly, so the problem must lie somewhere in your Apache/htaccess setup.

Hello @CP-Nico If you are not able to make it work with .htaccess then I would suggest to create a s3 bucket on AWS tier and enable CROS there. It is less technical and easy to work with.
