HTTP 504 timeout when uploading premium plugin zip on WordPress.com Premium

    Hi,

    I’m on WordPress.com Premium plan and trying to upload a premium plugin zip file (Amelia Pro, 31.5mb) via wp-admin → Plugins → Add New → Upload Plugin.

    Getting this error every time:

    Upload problem: http_error.
    An error occurred while installing the plugin.

    Network tab shows:

    Request URL: https://public-api.wordpress.com/rest/v1.1/sites/[site-id]/plugins/new
    HTTP 504 - Gateway Timeout
    Total request time: 3.1 minutes

    What I’ve tried:

    • Installed Big File Uploads plugin (set to 6GB) — still times out
    • Smaller plugins (Hello Dolly, ~10kb) install fine
    • Issue is only with large zip files
    • SFTP is not available on Premium plan

    Site: studio9312.wpcomstaging.com Plan: WordPress.com Premium (monthly)

    Is there any way to increase server execution time for plugin uploads on the Premium plan, or can support install it directly?

    Thanks

    The HTTP 504 Gateway Timeout error after exactly 3 minutes points to a server-side execution limit on the WordPress.com proxy layer, which cuts off the upload process before your 31.5MB Amelia Pro zip file can finish uploading and unzipping. Since custom PHP configurations like max_execution_time cannot be modified manually on the Premium plan, and SFTP access is restricted, plugins like ‘Big File Uploads’ won’t fix this because they can’t bypass those core network timeouts.To solve this without a hassle, download the Amelia Pro installation zip to your computer, extract it locally, and look inside the folder—premium plugins often bundle heavy documentation, demo data, or add-ons into the main download that cause the file size to bloat. If there is a smaller core plugin zip file inside (ideally under 20MB), try uploading just that core zip file through your dashboard. If the file is already stripped down and still times out, reply to this thread or open a direct ticket with support; a Happiness Engineer can bypass the proxy limits and upload the plugin directly to your site directory from the backend!
