When adding a domain ,nginx "restart failed" error occurs

I registered 339th domain in Hestia CP, but I get an nginx restart failure error. Even if I increase the server specification and capacity, I keep getting errors when I add 339th domain. How can I increase the limit. I’d appreciate it if you could tell me a solution.

Check the error logs

Where is the error logged?

I had the same error. But the following directory is empty

/var/log/nginx/domains/

/var/log/nginx/error.log

error.log is empty

ls /var/log/nginx/ shows

access.log error.log error.log.1 error.log.2.gz error.log.3.gz error.log.4.gz error.log.5.gz
