DNS resolution issue in Android Mobile App (under LAN) despite no issue in browser

I’m running a DNS to resolve local names when under Lan.

Home assistant fqdn is resolved as an Ipv4 address and ui opens in browser.

But not any more in Home Assistant Mobile App. Worked fine for few weeks but now seems unable to work.
