Hi, all

Having a weird one, and not able to specifically trace it to an nginx issue, though I'm not an expert there.

Getting this error:

2017/07/20 19:16:44 [crit] 21618#0: \*3 open() "/etc/nginx/client\_body\_temp/0000000001" failed (13: Permission denied), client: 10.10.0.200, server: kibana1.region1.ldap1.testdomain.local, request: "POST /elasticsearch/\_msearch HTTP/1.1", host: "kibana.region1.ldap1.testdomain.local", referrer: "[https://kibana.region1.ldap1.testdomain.local/app/kibana](https://kibana.region1.ldap1.testdomain.local/app/kibana)"

2017/07/20 19:16:44 [error] 21618#0: \*3 open() "/etc/nginx/html/50x.html" failed (13: Permission denied), client: 10.10.0.200, server: kibana1.region1.ldap1.testdomain.local, request: "POST /elasticsearch/\_msearch HTTP/1.1", host: "kibana.region1.ldap1.testdomain.local", referrer: "[https://kibana.region1.ldap1.testdomain.local/app/kibana](https://kibana.region1.ldap1.testdomain.local/app/kibana)"

This is a 1.9.9 build of nginx build with Kibana 5.3.0-1

This issue is not a bug. I found the problem, and it was rather ridiculous and a pain to track down.

The build scripts for the nginx front end neglected a permission on /etc/nginx.

This one's in the bag.

Same issue as [Visualization/Authorization Error when using dashboards with many visualizations](https://discuss.elastic.co/t/visualization-authorization-error-when-using-dashboards-with-many-visualizations/94001)

My apologies

Thanks for posting your solution, Mark! Glad you were able to figure it out. 🙂
