Requisição em API retorna 403

Boa tarde, estou usando um servidor no EC2 da aws, com SO amaxon linux 2 para montar um ambiente de homologação, nesses servidor tenho um nginx 1.24 onde configurei um site estatico feito em react, no location /, e no location /api tenho um proxy reverso apontando para um tomcat server, que tem uma api java 8 com springboot

        }

    }

}

esse é arquivo de configuração do nginx. Quando faço a requisição na api pelo postman, ou loccal na minha maquina, a requisição retorna 200, mas quando uso o front que está no próprio nginx, retorna 403. Alguem poderia me ajudar?
