Keputusan yang diperolehi dengan menjalankan arahan netstat pada pelayan adalah seperti berikut:
Saya tidak tahu bagaimana anda biasanya menyahpepijat masalah seperti ini? Terdapat juga soket domain UNIX Aktif (tanpa pelayan)
Adakah terdapat sebarang masalah dengan pasangan perkara di bawah ini?

Jika ralat 504 berlaku. Terutamanya, masa permintaan perkhidmatan entiti berikutnya dianggarkan agak besar. Malah, anda boleh mencuba ini dengan menambahkan beberapa parameter pada nginx anda. Gunakan fastcgi atau proksi terbalik untuk menambah tamat masa. Terdapat juga client_header_timeout, client_body_timeout, send_timeout.
