We've been using Cloudflare Gateway DNS since pandemic era pa noong bago palang ang service na to and this is the first time na nagkaroon kami ng ganitong issue. BTW, Gateway DNS is Cloudflare's equivalent to NextDNS at Adguard.
Bigla nalang syang hindi gumana sa Converge simula kahapon tapos today hindi na rin sya gumagana sa Smart.
Upon further investigation, kapag Converge Wifi or Smart mobile data connection ang gamit nagkakaroon ng "TLS Handshake Failed" error kapag nag attempt ng connection sa dalawang anycast IP address ng Gateway DNS based sa nakuha kong network logcat sa android phone. I tried using DITO and Globe tas gumagana sya ng maayos sa dalawang network na yan.
Could you guys try to test sa Converge or Smart ninyo ang Cloudflare Gateway DNS using Android's builtin Private DNS settings? You can input random characters followed by .cloudflare-gateway.com example: random123.cloudflare-gateway.com, don't worry because if the random hostname is not tied to a cloudflare account, it will act as unfiltered DNS using Cloudflare's 1.1.1.1.
Ps: Tried to report na din sa ISP pero puro basic troubleshooting lang pinapagawa nila.
