Upload to CDN fails with PHP 8.0 but works with PHP 7.4
-
Hey there,
When I try uploading any website assets to Amazon S3, the upload fails (and attempts to retry every 10 seconds). This happens with PHP version 8.0.3, but when downgrading to PHP 7.4.16, the upload to S3 works as intended. Here’s what I get in the PHP-FPM error log (similar in Nginx, but less verbose in those logs):

Thanks for your time!

Hello @tecca
We’ve made an update to the library for AWS SDK. You can test it here (in development): https://github.com/W3EDGE/w3-total-cache/releases/download/2.1.3-beta.1/w3-total-cache-2.1.3-beta.1.zip
We are still testing and it appears that the uploading is working as expected.
Let me know if you can test this and we would appreciate your feedback.
Thanks!
