Leverage browser caching nginx Not working?

I want to enable browser caching in nginx proxy server, for that, I followed, below stack overflow link, but it's not working, website images are not displaying after enabling browser caching,

link:- how to fix Leverage browser caching nginx? -https://stackoverflow.com/questions/47966400/how-to-fix-leverage-browser-caching-nginx/47976385#47976385

please help how to enable in nginx proxy server ?

404 not found is not an instructive error message for TTL < 0

            ## If the expire timestamp is negative that means that
            ## the item is not found or other error.
            [ $ttl -lt 0 ] && echo "404 Not found" && continue

Shouldn't this say something like "Expires set in the past"
