Why does the site freeze during a long cUrl request? Is Nginx+Apache+PHP on the server?

Question

PHP

The site uses cUrl, and the response of the remote server is quite long, but unfortunately this cannot be fixed. There is a bunch of Nginx + Apache + PHP on the virtual server, I don’t want to change it, since it copes with 95% of tasks. And the problem is this: while cUrl is working, the entire site hangs (sites with other domains at this moment come off on this server). Maybe the problem is in the Nginx settings? If necessary, I can post the Nginx config. I set up a bunch according to the instructions, since there is little experience. Ajax is NOT a solution, because it will also hang the site.

I agree with dimonchik2013 , you need to use queuing systems
