The implementation of the httpd application using enc28j60 found that the outgoing file was incomplete.
(Same code, did not appear when using dp83848)

When data__index_html[] is transmitted, the TCP connection ends actively.

The modification method is to add the following code in the <httpd.c> "http_send" function.

If(data_to_send == 0)

The specific location added is at line 1613.

//----- --------------------------Original code:
#if LWIP_HTTPD_SSI
  if (hs->ssi) {
    data_to_send = http_send_data_ssi(pcb, hs);
  } else
#endif /* LWIP_HTTPD_SSI */
  {
    data_to_send = http_send_data_nonssi(pcb, hs);
  }

  if ((hs->left == 0) && (fs_bytes_left(hs->handle) <= 0)) {
    /* We reached the end of the file so this request is done.
     This adds the FIN flag right into the last data segment. /
    LWIP_DEBUGF(HTTPD_DEBUG, ("End of file.\n"));
    http_eof(pcb, hs);
    return 0;
  }

//----------------------------- Modified code:
#if LWIP_HTTPD_SSI
  if (hs->ssi) {
    data_to_send = http_send_data_ssi(pcb, hs);
  } else
#endif /* LWIP_HTTPD_SSI */
  {
    data_to_send = http_send_data_nonssi(pcb, hs);
  }
  if(data_to_send == 0)    add code
  if ((hs->left == 0) && (fs_bytes_left(hs->handle) <= 0)) {
    /* We reached the end of the file so this request is done.
     This adds the FIN flag right into the last data segment. /
    LWIP_DEBUGF(HTTPD_DEBUG, ("End of file.\n"));
    http_eof(pcb, hs);
    return 0;
  }
