Windows and Apple devices can easily connect to the server, but private DNS connections cannot be established with Android devices. I've been using it for months and there was no problem, then suddenly it started to happen. Maybe it's because of the update.

Yeah this is truly frustrating... I've tried everything to get it working, like adding upstream DNS servers, editing android wifi parameters, reseting the router, generating new certificates for the domain... :/

This is not an issue with AdGuardHome, but rather an issue with the SSL certificate you're using. I struggled with this for a long time too. This explains the issue. Android seems to be much more picky about rejecting connections with the expired root in them.

To fix the issue I started using a different ACME SSL provider, not LetsEncrypt.

It's also discussed in more details here.
