I'd recommend to take a look on the proxy_intercept_errors directive [1],
it helps to intercept 300+ error codes and processing with the error_page
directive [2].

References
1. https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_intercept_errors
2. http://nginx.org/en/docs/http/ngx_http_core_module.html#error_page

Hope that helps.
