  I’m having trouble uploading image files to my WordPress site via the REST API endpoint:

  Whenever I attempt to upload an image above 300KB or so, the request times out. Smaller images mostly upload without issue. I’ve verified the following:

  • The file is well within the upload limits set in php.ini (upload_max_filesize is 512M, post_max_size is 516M).
  • My PHP version is 7.4.33 with Apache.
  • There’s no firewall or proxy I’m aware of that should be blocking the request.
  • I receive a 503 or timeout error, depending on the client used.
  • The hosting support could not find anything blocking my call. the same calls worked fine in the past on the same hosting.
  • Tried to disable all plugins, with no luck. same issue persists.

  Could this be a server-side configuration, or something in WordPress setup that’s interfering? any recommended setups or plugins to address this?

  Any guidance would be appreciated.
