tcpdump confirmou que não há trocas de pacotes com 127.0.0.1:9980, nem mesmo um TCP SYN. Como você pode ver, o Apache httpd pesquisa apenas o URL solicitado em seu diretório e retorna 404, em vez de passar a solicitação para 127.0.0.1 conforme solicitado na configuração. Qual é o problema?
< Proxy * > Blocos são, em geral, apenas necessários para proxies forward não reversos. Você pode removê-lo.
Se o proxy não estiver acontecendo, eu adicionaria um acesso específico e um log de erro do vhost para verificar a) se o pedido está realmente atingindo o vhost que você acha que é e b) se o caminho correto do URI está sendo solicitado.
Adicione estes na sua
Registros do CustomLog / port_9979_access_log Logs ErrorLog / port_9979_error_log
E olhe neles depois de fazer uma solicitação
