dhcpcd 10.5.2-1 unable to get IP address from Android access point

dhcpcd 10.5.2-1 times  out while getting the IP address from the access point of Android phones (tried with two phones, one running  Android 16) while it work with other devices (e.g. FritzBox 7530 AX). Launching it manually in debug mode after connecting to an an Android access point with wpa_supplicant the log says:

Downgrading to 10.3.2-1 fixes the problem:

Is there any know issue with dhcpcd 10.5 that can produce the above behavior?

Pleas use "code" tags to format your post.

It seems you are not the only one.

As seth mentions in the other thread that is most likely a regression (dhcpcd seems to ignore the offer from Android's DHCP server).

After updating to version 10.5.2-1 it works correctly for me.
