Regular expression length syntax not working?

[hyperion]

Hi

This is my second post. :-)

I have a regular expression in my location directive to match on a URL.

When I use:

http {
    ...
 
        location ~ ^/event/[0-9,A-Z]{16}/info$ {
            proxy_pass http://localhost:7777;
        }
    }
}

I don't get a match.

I have to manually repeat the [0-9,A-Z] sixteen times to get a match. 
Escaping the {} doesn't work either, i.e. /[0-9,A-Z]\{16\}/info

How can I use the {} syntax correctly?

nginx-V output, below.

nginx.conf used here:

All help appreciated.

Thank you.

Mik
