DNS over TLS (Private DNS) on Android suddenly stopped working overnight when connected via WiFi. This works fine when connected using Mobile data on the 3 network. Has something been changed or blocked at the Plusnet ISP level? I have confirmed this using both Cloudflare and NextDNS. I rebooted my router to rule that out. Please can someone else try setting up private DNS on Android 9 or higher using 1dot1dot1dot1.cloudflare-dns.com to confirm this is a widespread issue?
