could not build the proxy_headers_hash

[recived]

Здравствуйте. Не могу понять как решить проблему с ошибкой:
nginx: [emerg] could not build the proxy_headers_hash, you should increase
either proxy_headers_hash_max_size: 512 or proxy_headers_hash_bucket_size:
64
(nginx/1.1.19)
Подскажите пожалуйста.
