For this subscription, in "Hosting & DNS" > "Apache & nginx" > "Additional nginx directives",

proxy_buffer_size   128k;
proxy_buffers   4 256k;
proxy_busy_buffers_size   256k;

I have a installation guide here - Instruction - How to Install Magento 2.4 on Plesk but with docker. This might be outdated.

Eg - M2 2.4.7-p1 using OpenSearch not the ElasticSearch

Hope this will help.
