Why does the nginx BIO_new_file("/etc/ssl/certs/) error occur if I didn't specify ssl for any site?

Question

Nginx

I set up the second domain ssp.blackche.com (the first one is the default server "_") I didn’t indicate anywhere about using ssl in the server settings or in the global nginx settings
Why does the error
occur 2019/01/11 11:51:36 [emerg] 14542# 14542: BIO_new_file("/etc/ssl/certs/ssp_blackche_com.crt") failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/ssl/certs/ssp_blackche_com.crt' ,'r') error:2006D080:BIO routines:BIO_new_file:no such file)

Answer 1

Perhaps one of the includes still has ssl. View the config via nginx -T.
