dpd has no effect when using iOS anyconnect

[BitInn Admin]

In larger context: I would also like to ask, "which config may affect
client auto-reconnect function", currently AnyConnect always prompt me
with a message like "all reconnect attempts failed" (not the exact
wording, as the app is localized).

It does connect if tried manually, just not automatically. I only wish
the vpn log on client side is easier to read.

AnyConnect automatically disconnects the DTLS tunnel when the device goes to sleep to allow packets received over the TLS connection to wake the device. The DTLS tunnel is restored when the device resumes.
