# Font CDN issue

 * Hello,
 * So we have Total cache setup on a multisite installation. Two of the subsites
   use a similar font pack mandated by their theme. All files are uploaded to a 
   cloudfront CDN loaded from an S3 bucket (setup in total cache).
 * On one of the subsites, a key font regularly gets a CORS errors while all of 
   the other fonts are fine. Normally we have to purge that one font from the CDN
   to resolve however it keeps coming back.
 * Now when we try to clear the font we get the following error: Not a valid retry
   configuration argument.
 * How can we resolve this issue with the font CORS problem ?
 * Many thanks

 * Actually this looks like a more widespread issue with the CDN.
 * All of our upload queues have the same error.

 * Hello [@devksec](https://wordpress.org/support/users/devksec/)
 * I am sorry about the issue you are experiencing and I am happy to assist you 
   with this.
    Can you please share the website URL on which you are seeing these
   erros. The option “Add CORS header” needs to be enabled in Performance>CDN>Advanced.
   You also need to make sure to set the CORS configuration on AWS so please follow
   the instructions on this [link](https://stackoverflow.com/questions/39247055/cross-origin-resource-sharing-policy-font).
   Also, make sure to add the following rule at the top of the .htaccess:
 *     ```
       # Set CORS
       <FilesMatch "\.(ttf|ttc|otf|eot|woff|woff2|font.css)$">
       <IfModule mod_headers.c>
           Header set Access-Control-Allow-Origin "*"
       </IfModule>
       </FilesMatch>
       # Set CORS
       ```
   
 * I hope this helps!

 * Hello,
 * Thanks again for your support!
 * The font URL is: [https://cdn2.ksec.co.uk/wp-content/fonts/inter/UcCO3FwrK3iLTeHuS_fvQtMwCp50KnMw2boKoduKmMEVuLyfAZ9hjp-Ek-_0ew.woff](https://cdn2.ksec.co.uk/wp-content/fonts/inter/UcCO3FwrK3iLTeHuS_fvQtMwCp50KnMw2boKoduKmMEVuLyfAZ9hjp-Ek-_0ew.woff)
   
   I’ve managed to temp fix this by clearing the CDN cache again.
 * The CORS header is configured and works for every other file in the CDN, including
   WOFF fonts. The CDN behaviour link references the legacy cache settings in AWS.
   Does total cache support the updated “cache policy and origin request policy”
   instead of legacy?
 * We have the following in our .htaccess:
 *     ```
       <IfModule mod_headers.c>
           Header set Access-Control-Allow-Origin "*"
       </IfModule>
       ```
   
 * We’re still getting “Error: Not a valid retry configuration argument.” when trying
   to test the CDN config & upload anything to the S3 CDN.
 * Many Thanks

 * The “Not a valid retry configuration” seems to be generated fromthe AWS SDK code“
   ConfigurationProvider.php”
 * * Unwraps a configuration object in whatever valid form it is in,
    * always returning
   a ConfigurationInterface object. * * [@param](https://wordpress.org/support/users/param/)
   mixed $config * [@return](https://wordpress.org/support/users/return/) ConfigurationInterface*@
   throws \InvalidArgumentException */ public static function unwrap($config) { 
   if (is_callable($config)) { $config = $config(); } if ($config instanceof PromiseInterface){
   $config = $config->wait(); } if ($config instanceof ConfigurationInterface) {
   return $config; }
 *  // An integer value for this config indicates the legacy ‘retries’
    // config
   option, which is incremented to translate to max attempts if (is_int($config)){
   return new Configuration(‘legacy’, $config + 1); }
 *  if (is_array($config) && isset($config[‘mode’])) {
    $maxAttempts = isset($config[‘
   max_attempts’]) ? $config[‘max_attempts’] : self::DEFAULT_MAX_ATTEMPTS; return
   new Configuration($config[‘mode’], $maxAttempts); }
 *  throw new \InvalidArgumentException(‘Not a valid retry configuration’
    . ‘ argument.’);}
 * It looks like it started 19 days ago and the S3 CDN no longer works.

 * Hello [@devksec](https://wordpress.org/support/users/devksec/)
 * Thank you for the information.
    The AWS library version 3.183.0 was updated in
   the latest 2.1.3 version of W3 Total Cache 3 weeks ago. Can you please share 
   the PHP version you are using? Thanks!

 * Hello [@devksec](https://wordpress.org/support/users/devksec/)
 * Thank you for the information.
    Please try to re-authorize the CDN and see if
   the issue persists. I’ll try to replicate the issue. YOu might want to try upgrading
   the PHP to 8.0 Thanks!

 * So we cannot authorize it at all as that error is produced when trying to “Test
   S3 upload & Cloudfront distribution”.
 * We’ve even tried new keys but it seems that the AWS config isn’t being accepted
   by the AWS SDK.

 * Hello [@devksec](https://wordpress.org/support/users/devksec/)
 * Just to confirm, this happens only on a single subsite?
    Are you referring to:`
   vendor/aws/aws-sdk-php/src/Retry/ConfigurationProvider.php`? Thanks!

 * So this is with a multisite setup and they’re all using the same config.
 * Yes thats correct

 * Hello [@devksec](https://wordpress.org/support/users/devksec/)
 * Thank you for the information.
    Seems there is some kind of issue with the CDN
   configuration (On the AWS before trying to connect with W3TC) Can you please 
   double-check the config and try creating a new bucket? Thanks!

 * So we’ve setup the CDN + S3 to default however still getting the same error when
   trying to test access.
 * Not sure if there is some issue with the Total cache config ?

 * This looks like its being caused by a conflict with WP-Activity logger … Disabling
   the plugin resolves the issue.
 * I’ve raised this with their dev team.

 * Hello [@devksec](https://wordpress.org/support/users/devksec/)
 * Thank you for the information.
    So it seems that is a Library conflict with the
   other plugin. You can force W3TC not to load its own copy by adding: `define('
   W3TC_SKIPLIB_AWS', true);` I hope this helps!
