Error Generating CSR using openSSL



I am trying to install a domain cert into my PRTG server following the steps listed herehttps://kb.paessler.com/en/topic/283-how-can-i-use-a-trusted-ssl-certificate-with-the-prtg-web-interface#reply-713. When I run the openssl req -nodes -newkey rsa:2048 -keyout prtg.key -out prtg.csr -config openssl.cfg from the \bin directory I get the blow error.

Can't open openssl.cfg for reading, No such file or directory 860:error:02001002:system library:fopen:No such file or directory:crypto\bio\bss_file.c:69:fopen('openssl.cfg','r') 860:error:2006D080:BIO routines:BIO_new_file:no such file:crypto\bio\bss_file.c:76:

Is it surely openssl.cfg and not openssl.cnf, as in their github repository? :)

openssl req -nodes -newkey rsa:2048 -keyout prtg.key -out prtg.csr -config openssl.cfg is what I had not openssl.cnf

it is .cnf and in my installation of openssl the path to the file was C:\Program Files (x86)\Common Files\SSL\ so I had to setup an environment variable.

Thanks for the help
