We have created a script for executing an API-RPC query via PHP and are trying to launch it via browser.

Instead of successful reply we receive a "failed to get response from server" error, however the subscription gets created.


Apache server is being restarted during the subscription creation, which aborts the server session.


The issue will be fixed in a future update for which a new Knowledgebase article will be created. You may subscribe for new articles on Parallels Plesk Panel Product if you wish to receive notifications about their creation.

Workaround 1 (recommended)

Enable Apache graceful restart as per this article:
