FastCGI, nginx: How to fix archive unpacking error?

Question

PHP

a zip archive is uploaded to the server, then it must be unpacked and a series of actions (images will be transferred to the right place, as well as data will be uploaded from xml to the online store)
during unloading, the server returns a number of technical parameters and an error message.
Server API: fpm-fcgi
Memory limit: 512M
Maximup POST size: 500M
PHP version 5.6.35
FastCGI site php mode (Nginx + PHP-FPM)
In error.log I found this line with an error:
FastCGI sent in stderr:
" PHP message:
Error: Failed open archive /var/www/blablabla/catalog/v8_11D1_35f.zip
with error code 19" while reading response header from upstream
Tell me what to do and where to dig first, thanks!
