Hi

I'm getting random error code 500 when serving from cache, here is an example:

1554735637.102 10.210.44.205 57635 "GET kCache/.../seg-101341803-s32-v1-a1.ts HTTP/1.1" 830 "" "Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko" 200 897748 0.052 HIT - https
1554735766.426 10.210.184.156 57413 "GET kCache/.../seg-101341803-s32-v1-a1.ts HTTP/1.1" 602 "" "Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko" 500 0 0.000 HIT - https

Unfortunately nginx error log doesn't show anything, any idea why?

Thanks
Guy.

I'm running nginx/1.8
here is the config:

proxy_cache_path /cache/live levels=1:2 keys_zone=one:20m inactive=1d max_size=5512M ;


location ~ ^/kCache/(?<url>.*(?<cache_key>(?<=/kCache/).*).*)$ {

proxy_cache_key $cache_key;
proxy_pass http://proxy_backend/$scheme://$url$is_args$args;
}
