Nginx try_files not working for default index.html
The last element of the try_files statement is the default action, which is either a URI or a response code. The /index.html starts a search for a new location to process the request, and ends up back at the start, so you have a redirection loop.
You can fix the problem by making /index.html a file term instead. For example:
try_files /$geoip_country_code/index.html /index.html =404;The =404 is never actioned, because /index.html always exists.
Personally, I would use a generic solution:
try_files /$geoip_country_code$uri $uri /index.html;See this document for more.
